Ability Book

Ability Books are special consumable items that drop primarily from monsters, dungeons and elite challenges, with some exceptions. By consuming a book or ‘learning’ an ability, the player has permanent knowledge of that ability.

There are abilities for all three combat styles, defensive abilities and team support abilities which may or may not require the use of runes, ranged ammo, and/or particular weapon types.

Book Icon/Name	Ability	Style	Description	Drop Location
Notes On Acid - I	Acid Splash	Magic	Splash an enemy with acid, heavily reducing their defenses.	Fallen Academy
Notes On Acid - II	Acid Wave	Magic	Splash your enemies with acid, heavily reducing their defenses.	Fallen Academy
Apocalyptic Tome	Apocalyptic Ritual	Magic	Release a hellish wave of sulfuric flames to destroy nearly everything in its wake. Magic of this scale may destroy the entire enemy party, but the incredibly long incantation time leaves the caster wide open to counter attacks.	Barrows Cache
Armor and Its Weaknesses	Armor Rend	Melee	Tear at the enemy armor, reducing its effectiveness.	Overgrown Woods

Ice, Ice, Ice	Icy Shell	Defense	Temporarily encase yourself in a shell of magical ice, increasing protection, resistance, and defensive ice affinity at the cost of agility. Melts very quickly!	RFI
Combat Manual - Volume 4	Impale	Melee	An impaling attack that can hit up to 2 enemies at once.	RFI
Smoke and Mirrors	Invisibility	Defense	Actually, you're probably closer to just a little translucent, but if you claim to be invisible to sound cooler, that's okay too.	Barrows Cache

Uses

If an ability is already learned, then the book in question can not be consumed. As ability books are not currently tradeable in the Marketplace, they can be sold to the npc vendor, burned for Heat, or sometimes researched for their Runic Dust.
