Chain Reaction Enchantment

Chain Reaction is an Offensive enchantment for ranged weapons that multiplies your arrows. Successful ranged hits have a chance to fire additional projectiles at nearby enemies, spreading your damage across a crowd instead of concentrating it on one target. Against packed mobs, a single arrow can snowball into a volley.

Both the chance and the projectile count scale with tier: Tier I gives a 20% chance to spawn 4 additional projectiles, Tier II raises it to 30% for 6 projectiles, and Tier III reaches a 40% chance for 8 additional projectiles. It applies only to ranged weapons, so dedicated archers are its natural audience.

Bow builds that fight at mid-to-long range benefit most — the more enemies your arrows reach, the more triggers you get. It stacks conceptually with other projectile enchantments such as Piercing (to line up more hits), Ricochet (to bounce between targets), and Thundering Enchantment for extra splash damage on top of the extra shots.

The book drops from the enchantment book pool in Ravines, and the Enchantsmith in Wading Rainy Plains applies and upgrades it — see Minecraft Dungeons II Enchanting Guide. Tier I costs 3 enchantment points and 1 Echo Shard, Tier II costs 5 points and 1 shard, Tier III costs 7 points and 1 shard (15 points and 3 shards total to max). The merchant's level gates higher tiers and re-rolling; disenchanting is free and refunds all points but not Echo Shards.
