Precision Effect

Precision is an offensive gear effect in Minecraft Dungeons II that increases the chance of critical hits with melee attacks. It is the melee counterpart to Aim Effect, which does the same for ranged attacks.
The bonus grows from 10% at tier I through 15% at tier II and 20% at tier III, reaching 25% at the unique tier. As a flat chance added to your base rate, each tier makes crits noticeably more frequent on fast-swinging weapons.
Melee crit builds are its natural home. Critical Edge Effect makes those crits hit harder, and Critical Hit Effect adds general crit chance that stacks with it — together they turn any fast melee weapon into a crit machine. High-damage slow weapons also benefit, since each rare crit then hits for enormous numbers.
Tier availability follows the standard threat curve: tier I only below threat 3, tier III from threat 6, and tier III as common as tier II from threat 15. Common items never roll effects; rare items carry one and special items two.
