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.

They say that deep within the forests of The Gloom lies a mysterious hedge maze, expanding as far as the eye can see.
While most people are sane enough not to enter, those that do never come out the same, if at all.
The Hedge forever changes them... empowers them... to what end, nobody knows.
A Hedgeknight is a worthy foe, capable of laying wound upon wound on enemies, and inflicting them with the most dangerous of poisons.

This addon adds in the Hedgeknight Class, a Two-Handed warrior who uses the power of 'The Hedge' to augment his power with various summons and buffs.

Forum discussion thread: http://forums.te4.org/viewtopic.php?f=50&t=48329

Phoenix Knight: Powerful warriors who blast their foes with solar fire while calling healing light upon their allies. Their solar fire attacks will strike as either fire or light damage, whichever will hit their target the hardest, and their potent healing and cleansing abilities make them tough opponents to bring down.

Mind Knight: Psionic warriors who strengthen their mental abilities by tapping into their inner magic. Adept at telekinesis, telepathy, and teleportation, they are mobile scouts who can quickly get a lay of the land and sow chaos among their foes with physical and mental debilitations, or even outright compulsions.

Storm Knight: Swift skirmishers who rely on extreme mobility and powerful lightning magic to strike their foes down and avoid reprisals. Extremely fast and difficult to pin down, they can cast entire enemy units into disarray with their wealth of area attacks. All mage knights can cast while they fight, but experienced storm knights are also able to fight while they move.

Earth Knight: The heaviest of infantry, earth knights hammer their foes with physical and natural forces while shielding themselves with the power of the earth. Highly resilient in the face of any attack, earth knights provide a slow and steady offense supported by powerful gemstone shields and the endurance of a living mountain.

Sea Knight: Healers first, fighters second, battle mages a somewhat distant third, while sea knights lack the raw offensive power of other mage knights, they make up for it with amazing personal defense and recovery abilities. And though their attacks may be individually weak, like the sea itself, they are able to wear down even the strongest defenses eventually, eroding their opponents away with gradually strengthening spells, making them terrors in a battle of attrition.

Mana Knight: Experimenting pioneers who do amazing things with raw magical energy. They have the most conventional magical training of the mage knights, even if they sometimes put it to unconventional use. Their arcane attacks can overwhelm the powers of other spellcasters, and while they lack the scope of power of full-fledged archmages, they are masters of the fundamentals of the various arcane schools.
