Lens-Maker's Glasses
Common item (white)
10% of your hits are critical and do double damage. Each extra pair adds 10%; with ten, every hit is a crit.
Game text: «Your attacks have a 10% (+10% per stack) chance to 'Critically Strike', dealing double damage.»
Stacking: Capped at 10: with ten, every hit crits. The eleventh does nothing, unless you plan to turn them into Lost Seer's Lenses.
Watch out: On Railgunner they give no crits: each pair adds 10% crit damage instead. Crit chance does not depend on the hit's proc coefficient.
