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.

Plenum ToolTip: Enhanced tooltip display for ToME version 2.4 for ToME 1.3.0

This addon replaces the normal tooltip for actors in TOME with a more detailed description of monster abilities and characteristics. It adds to the standard tooltip detailed information on speed, main-hand, off-hand, and ranged damage, and damage modifiers and extra crit power, including damage penetration and damage affinities, plus retaliation damage, depending on what options are selected (from a tab in Game Options menu). This makes it much easier to inspect multiple monsters and quickly identify the most threatening. By holding a meta-key (ctrl, alt, or shift) and hovering the mouse over a monster, information on its status immunities and talents is displayed.

In addition, information on temporary terrain features (like smoke and darkness) and map effects (from spells and the like) will be displayed in the terrain tooltip if the appropriate options are enabled.

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'.

Available modes:
• 'Always Viligant' always stops running when a hostile creature is seen via telepathy.
• 'Original' is standard ToME auto-explore behavior, which ignores telepathy when running or auto-exploring.

• Compatible with ToME v1.6.0

Notes:
Folks who have helped with bugfixes over the years:
Reca♥den
St_ranger_er
zizzo

• 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 replaces the default tactical borders with a verson that more clearly shows the healthbars while making target identification quick and easy.

+++ This addon only works for new characters, unless you edit your save file+++

Instructions for save file editing:

Locate your save folder - (Generally in C:\users\*username*)

( The name of you save folder inside your *username* directory is T-Engine )

BACKUP YOUR T-Engine folder TO A SAFE LOCATION - ( You can copy and paste it on your desktop )

Inside your *username* directory, open your T-Engine folder
Open the 4.0 Folder
Open the Save Folder
Look for the folder with your character's name you wish to edit and open it.
Look for and open your desc.lua file ( You can use notepad, but it may be easier to download and install something like Notepad++ )

Locate the line that looks like the following:
addons = {'ashes-urhrok', 'items-vault', 'steamui', 'stone-wardens'}

Add inside the { } the following 'myth-minimalist-ui' so that it now looks like:
addons = {'ashes-urhrok', 'items-vault', 'steamui', 'myth-tactical-borders', 'stone-wardens'}

( Keep in mind the above will look different based on what addons you have installed )

Save your desc.lua and exit the file.
