Arcane Lore

Arcane Lore gives bonus spell critical chance and spell critical multiplier to all spells. Notably, this is the only way to gain spell critical strike with spells of unusual damage type, such as the bludgeoning damage from Ice Storm, or the slashing damage from Blade Barrier. All damage spells, including healing and repair spells are effected by Arcane lore.

Like other lore effects, this bonus stacks with similar enhancements.

Arcane Lore

 * Elfcrafted Robe
 * Epic Ornamented Dagger (Tier 2 and higher)
 * Bracelet of Madness

Greater Arcane Lore

 * Skiver
 * Green Blade
 * Blue Dragonscale Robe
 * Noxious Embers
 * Mindfury Symbiont

Note
Major and Superior Arcane Lore currently do not exist in game. However, the Archmage set bonus (Rahkir's Sash and Rahkir's Ring) includes a +0.50x increase to critical damage multiplier for all spells. By having both Greater Arcane Lore and this set bonus, you virtually benefit from Major Arcane Lore, which is +9% and +0.50x.
