Barachim have been added, a new species that moves slowly but has good aptitudes, a powerful Hop ability, and can see one tile more than other species. Ogres have had their aptitudes and stats reworked, allowing them to be more proficient spell-casters and not just melee brutes, and mummies have a much higher spell-casting aptitude.
Two new spells have been added: Ignition, a high level Fire Magic spell that drops a weakened Fireball on every monster in view, leaving the player and their allies unaffected, and Poisonous Vapours, a Poison/Air spell in the Venom Mage starting book the creates a very short-lived poisonous cloud on a single monster.
Scarves have been added, which are auxiliary armour for the cloak slot that has 0 AC and can’t be enchanted, but have special powerful egos like Repel Missiles, Cloud Immunity, Resistance (rF+ & rC+), and Spirit Shield. Mutation potions are now the only mutation-changing potion, and each quaff cures multiple existing mutations and grants several new ones. Additionally, spells formerly found on rods have been moved to wands of clouds and scattershot and the new rod of lightning XP evocable, and other wands have had their ranges and effects adjusted.
Many new dangerous vaults have been added, including an epic level-wide Depths vault as well as tricky loot vaults using the new one-way transporter dungeon feature. The Tomb of Ancients now features more dangerous one-way stairs that don’t allow easy, immediate return, and the treasure walls of the Slime Pits now always breach when the Royal Jelly dies.
A new noise meter now shows the relative loudness of each action, and in console mode this can be replaced by a bar showing the glyph of each equipped item. Stash searches now exclude distant duplicate matches of vanilla weapons, armour and ammo by default. Finally, the mouse can now be used in WebTiles by default and the species selection menu is reworked to have groupings in “simple”, “intermediate”, and “advanced” categories.
