v1.0.0
Places 'Marson's All-Seeing Eye' in your character's inventory which gives telepathy:all at +10 range when carried (20 range total under normal conditions).

I created this so I could experiment with Madness without the need for a crazy amount of scouting. This is an extreme solution to scouting tedium as it also sees through invisibility and stealth as well. I may come up with a middle-ground solution after mucking with this a bit.

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.

Other addons that affect these files might not be compatible.

Adds a new command 'Rest for a specific number of turns', initially bound to <shift-r> (which can be rebound to your preferred key in the usual manner). A dialog will pop up for you to enter the number of turns you wish to rest.

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

Prodigies have minimal requirements and you can get one at level 1.

Do you dislike it, when your escortees die on harder difficulties at the zone in, without you being able to help them? Do you sometimes feel as if money was worth little to nothing in Maj'Eyal? If so, this addon might help you. The library of Last Hope now sells seven Tomes with on-use-rewards, that mirror those of seven escort-types. The library of Elvala sells two (very expensive) tomes, that lead to even greater rewards after using them.

Fixed: talent types are now known, but not learned

This addon adjusts the way friendly NPC's react to hostile actions by the player.

In most cases, the personal reaction of an NPC to the player (friendly/neutral/hostile) will slowly recover (by 10% each turn, minimum 1 point) back to it's default value over time. If the player doesn't further aggravate the NPC, it will eventually become neutral/friendly again. (Though it will still probably have the player targeted, depending on its ai settings which are not addressed in this addon.) The exception is if the player kills another friendly NPC within LOS, which will result in the NPC becoming permanently hostile to the player in most cases.

Putting a detrimental status effect on the NPC will create a -25 (negative) reaction to the player (in addition to the penalties from any damage caused).

For those who think the Homosuperior race by gkjzhgffjh is not easy enough.

This adds the Spell/Conveyance tree as a reward for completing the Tempest Peak questline for Angolwen. All the code is borrowed from DG's own, and thus everything works the same as antimagic characters getting Fungus.

This belt removes breathing because it makes you undead but ghouls still breathe?! Howgash! GHOULS DONT BREATHE!!

Adds a new game menu option "Show known Landmarks", which presents a list of landmarks (up/down stairs, golden chests, zone entrances and the like) that you've seen on the current level and allows you to go to them or view them on the map.  You can also set your own landmarks for later reference by right-clicking on the map and choosing "Set landmark".

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

Improves the default sort order of items in the player's inventory.

Changes the color of the highlight on Arcane and Arcane Disrupting items in the Transmogrification chest.
Items powered by arcane forces are highlighted in purple. Items infused by Arcane Disrupting Forces are highlighted in red. (I couldn't make it pink because the game kept changing the color)
I made this addon to make looking through large amounts of items a bit quicker if you're a mage or antimagic.

Special thanks to Marson. Wouldn't have been able to get this addon going if it weren't for his help and tips throughout.

Adds many new spells for Necromancer and modifies many existing spells, effects and minions. See thread for full details.

Greatly enhances rate of point gain for talents, generics, stats, categories and even prodigies.

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.
