This is a stand-alone Quality of Life pack that improves some minor things about ToME gameplay.
This pack improves visibility of status effects by adding particles to certain effect types (such as "dizzy stars" for stuns and confusions, or green bubbles for poisons).
Background: It is otherwise difficult to tell if or when certain effects procced or not, and it is also kind of obnoxious having to check each and every enemy for whether they're affected by something or not.
Stability: Very High

• Features can be toggled in: "(Menu)" > "Game Options" --> "[Nekarcos]"

This is a stand-alone Quality of Life pack that improves some minor things about ToME gameplay.
This pack makes size categories VISIBLY apparant. To be clearer-- A "Tiny" ant will now look SIGNIFICANTLY smaller than, say... A "Big" bear.
Background: I know-- It's so obvious, right?? For the longest time, I've wanted to make this add-on-- But it was only now that I could confirm its stability.
Stability: Very High

• Features can be toggled in: "(Menu)" > "Game Options" --> "[Nekarcos]"

Improves the "Press <control> to compare" functionality for objects.  New features:

• When pressing <control>, a note at the top of the text will tell you which object in your equipment is being compared against the current item.
• While holding <control>, tapping <shift> will cycle through the objects in your equipment that the current item can be compared to.  Useful when wearing two rings, dual-wielding, or using the second weapon set.
• (new in v3) Runes and inscriptions in your inventory or store inventories can be compared via <control> to corresponding inscriptions on your body.

Also available as part of the ZOmnibus Addon Pack and ZOmnibus Lite.

This addon makes items description easier to read and determine on a glance it's usefulness
- sorts all stats by category - DPS/DEF/MISC
- item's passive power always the same blue color (not a random blue-yellow-pink-green)
- item's usable power - always yellow
- all rarity categories are displayed
- encumbrance value moved to the right under item name
- "on hit" powers always green
- "Stats" have an ornage highlight and placed before others because it's most important one
- Removed many extra-explain details, which any veteran player would not want to read each time
for example, stat "S.pwr/crit" shorten from "Spellpower on spell critical (stacks up to 3 times)"
means you do remember that it can stack only 3 times, and is not so super important anyway
- DLC supported - Orcs/Ashes
- few bug-fixes along the way

Most important thing to remember
- Requirements only shown for those you don't meet. If you want to see all reqs - hold CTRL
- "Phasing" stat means - "Damage Shield penetration", the name was taken from the source and looks good to me, and short enough
- The "-" minus sign at the end of stat mean immunity or reduction of some sort, for example "Blind-" = "Blindness immunity",
- "Max.summ" = Max wilder summons
- "Summ.HP.reg" = Life regen bonus (wilder-summons)
- "Def/telep" = Defense after a teleport
- "Res/telep" = Resist all after a teleport
- "Dur/telep" = New effects duration reduction after a teleport

it's not recommended to use this mod if you'r new to the game

Modifies the character creation dialog to bypass the lock check for races and classes, allowing characters to be created using locked races and classes. Doesn't actually unlock anything.

Frequently Asked Questions:

• Hey, the character creation dialog still says I have locked races/classes! What gives?
• Will this prevent me from unlocking things?
• The latest version of the game has a new locked race/class. Will I need a new version of this addon to access it?
• What the heck is this Runic Golem thing?

Important: this addon will have no effect if left unconfigured! Please read the description!

Recommended settings:

• Requested FPS: 30
• Resting divider: 10
• Running divider: 5

Description:

Enables faster run/resting by use of FPS dividers.

These dividers simply divide the game's requested FPS by their respective values while resting or running. After starting a new game or loading a saved character, configure this addon by hitting escape -> video options. Setting these dividers to something greater than one can substantially reduce the amount of time required to finish resting/running on older computers.

Just be careful when resting on an escort mission...

Changelog:

See the forum discussion for the changelog.

Adds a suitably spleen-venting option to the Eidolon plane death chat, and an "Exit game" option to the death dialog.

Version 3.0: Compatible with ToME 1.5.0

This addon supports game play for character levels higher than 50, primarily for the infinite dungeon (I.D.). This implements a number of subtle changes, rescaling game mechanics and balance for character levels above 50 in the Maj'Eyal, Infinite, and Arena campaigns for ToME. The intent is to make it possible (though certainly not easy) to reach level 500 of the Infinite Dungeon. This is not a nerf or a buff to game difficulty per se, but, rather, an extension of the well-balanced game play from the Maj'Eyal campaign to higher levels.

Some talents and status effects have been adjusted to accommodate the higher character levels possible. You can see a summary of these by checking the "Infinite500" tab in Game Options.

Once a character enters the I.D., the level 50 cap is removed and normal stats-per-level progression is enabled from level 51 onward. The limit on how high primary stats may be trained is removed (limited by character level as normal) and dependent computed value limits are also appropriately increased. No additional Prodigies are gained automatically after level 50. (Note that additional category points and (rarely) Prodigies can be gained by completing I.D. challenges.) Talent mastery levels can be improved more than once, and talent levels are unlearnable as normal in the I.D.

NPC levels in the I.D. have been adjusted to be compatible with higher game difficulty settings.

Most monsters and bosses from the Maj'Eyal campaign are imported into the I.D. along with their respective unique drops.

Traps have been added back to the I.D.

Isolated shops can appear randomly in the I.D. There is guaranteed to be at least one shop on level 1, and they become more common for the first few levels, and then more rare with depth.

Random escorts may be randomly generated on each level in the I.D. unless a challenge has been started, until the normal number (9) have been attempted.

The lichform quest is completed in the I.D. with a new random drop instead of automatically being completed at the appropriate step. There is a new greater vault in the I.D. that affects this quest.

The Corruption/Hexes tree can be learned from a new random drop.

Most major events from the Maj'Eyal campaign are enabled in the I.D., and there is a new event that can award the cursed-aura tree.

Undead characters starting in the I.D. begin with an artefact cloak. This is similar to the Cloak of Deception, but its stats scale with character level and it can spawn randomly for other characters.

This addon incorporates some modified game mechanics:
The ability to shrug off critical hits has been changed. Instead of using the percent value to ignore crits completely, it reduces the crit multiplier by the same amount to a minimum of 100%.

Modified checkHit and checkHitOld functions are employed that allow for wider level differences between opponents (see http://forums.te4.org/viewtopic.php?f=36&t=35229).
Saving throws have been modified slightly to make them more effective at reducing the duration of status effects you fail to save against. (See http://forums.te4.org/viewtopic.php?f=36&t=36715 for details.)

Things planned for the future: scaling of world artefacts with character level, map effects with dungeon level.

Quality of Life improvements for resting and auto-exploring.

v3.5.0 *** FOR ToME v1.6.5 ***
This is a fork (with permission) of Marson's auto-explore and rest tweaks. It includes as well C.Lowe/CaptainTrip's improvements as well. It does not include, but recommends also using Johnny0's Faster RRE add-on for even better rest and auto-explore experience. This add-on contains numerous Quality of Life improvements designed to make resting and auto-exploring easier to use, brings the add-on overall up to being compatible with 1.6.x, and generally seeks to remove it being more optimal to do timed rests or manual recovery (particularly to help higher difficulty level and players without Faster RRE). Cleaned up feature list in this take, to make it easier to see what it does.

It is recommended to turn off Marson's Rest and Auto-Explore as well as C.Lowe's Rest Tweaks if using. This addon is meant to include all of them.

Latest Update Notes:
• Changed steam sustain behavior to match current gameplay. Before sustains tended to shut off when available resource was 0, now they don't seem to do so. This will now only turn off sustains that drain steam if steam is going below 0, so as to get to a steady finish state.
• Fix minor bug where stealth enabling was always on if you had it.
• Added new option to ignore quest members when resting or exploring. It defaults to off but for those folks that know they want to ignore those quest allies and rest a bit.

Existing Features:
• removed First Sighting and Reset on Rest. Someone can patch them in if they'd like it back, but I'm not really keeping them alive.
• Fixed actor bugs causing Elemental Surge to never reset. Thanks Reca♥den.
• Fixed bug with Paradox Spacetime Tuning from 1.5.5. This may rebreak posessors with paradox, hard to kinda test.
• Mostly verified working on 1.6.0
• Compatibility with restart sustains. Thanks zizzo.
• When resting, it will check for infusions and runes that could be used to accelerate HP, Mana, or Equilibrium (via Ancestral Life or Meditation) recovery. If the acceleration appears significant, it will use them, rotating from first available infusion or rune outward. In experiment, I found this often reduced rest turn time by 50-80 percent, improving the more drained the resource was. Particularly helpful for Mana, as it avoids trade-off advantages of short term resting (for increased mana regen) + rune use by just handling that more optimal play for you automatically without breaking rest.
• Support for steam implants, with usual checkboxes. This may not always be faster based on steam sustains that may disable after the initial round of rest and steam implants having very long cooldowns (30+ turns) and steam's resource max being pretty small. It tries to be conservative on that, so will most likely help for cases where your functional steam regen rate is < 2.00 and never activate for things much above it. I found I was often getting 5-20 steam per turn, which makes the implant support useless.
• Supports for medical healing salve injectors. Cooldown measurements are a bit odd here, since they can range from 5-20 depending on injector. Went with 10 as a happy medium for how many turns of natural regen is considered to be equal to the cooldown cost of using it.
• Adding support to auto-stealth if available and not stealthed.
• Option for ignoring small damage when moving and resting, basically if it is <5%, it will ignore it by default, prevent small DoTs from preventing rest.
• Options added to control whether or not to use inscriptions to accelerate recovery of things.
• Fixes a ToME bug that can cause autoexplore or running to move only a single square and hang if used immediately after killing an enemy.
• Lore discovery will only stop autoexplore if it triggers a popup.
• Autoexplore will ignore Exploratory/Infinite Farportal return portals until the entire level has been explored.
• Ignores special terrain features such as Font of Healing after they are first discovered.
• Ignores open chests and alt Maze floor cracks.
• Rest and AE ask for confirmation if you have an escort in your party.
• Ignore already activated pedestals.
• Checks for and waits on any rechargeable items.
• Checks for and reloads any ammo in offhand quiver.
• Waits for cooldowns of talents set to auto-use.
• Waits for depleted air to replenish.
• Combines all checks into a single instance of rest, rather than having cooldowns etc. require a second resting phase.

Determines how auto-explore and running respond to telepathy, including mouse moves. Regardless of the setting, hostiles seen via telepathy will not halt resting or the Rod of Recall, nor trigger automated talents. Unique or powerful monsters (rank > 3) will always trigger a halt to running when they are spotted via telepathy for any mode except 'Original'.

• Compatible with ToME v1.6.0

Notes:

• Telepathy will not prevent auto-exploring the way normal sight will. If a halt is triggered by telepathy, hitting auto-explore again will move you at least one more square in the direction of the auto-explore path. If in 'Always Viligant' mode and a hostile is within telepathic sight (but not normal sight), you will auto-explore in 1 square per keypress increments.

This addon add a column to inventory which show items Tier and allows sorting to show higher Tier first
Useful when in late game you interested only in Tier 5 items

There is an option under "Game Setting"->UI->Sort Items by Tier by default
which is if enabled makes sorting by Tier default when opening Inventory
Otherwise click on 'T' to sort items by Tier

items which is going to be transmo- and of type scroll (rune,infusion..), tinker or other without Tier specified will be placed at the top of the inventory to avoid occasional transmo of valuables

This mod is safe to use without starting new game
