Deadeye's Resolve I

Physical damage increased by 50%.

While channeling Rapid Fire, gain 25% damage reduction.

Your deadeye focus sharpens. Rapid Fire shoots 30% faster, deals double damage, and its arrows now pierce up to 3 targets.

Each cleared boss encounter of level 40 and higher has a 2% chance to drop a rune (1.5% on mini-boss stages). On Inferno 1.758% of those runes are Set Runes before the stage's loot bonus and Item Find, which raise it; on Normal and Nightmare no Set Rune drops. Only runes for the current hero's class drop.
