Thundering Enchantment

Thundering is an offensive enchantment usable on both melee and ranged weapons. Attacks have a chance to spread lightning damage to nearby enemies, sparking arcs that turn single hits into crowd damage without requiring a finished combo or a special trigger.

Both the chance and the damage climb with rank. At Tier I there is a 25% chance for 15% of weapon damage to spread as lightning; Tier II raises it to a 33% chance for 30%; at Tier III the effect fires half the time, spreading 50% of weapon damage as lightning. The chance-based design is the tradeoff: it can feel inconsistent, but across a fight it adds a steady stream of bonus area damage.

It earns its A tier rating, and it is the standout pick for weapons that rarely finish a full combo, since it needs no combo completion to fire. Melee weapons that spam quick hits and bows that chip crowds both qualify. Players weighing alternatives can compare Lightning Surge for a status-inflicting wave, Chain Reaction Enchantment for explosive chains, or Swirling Enchantment for guaranteed flat damage on a cooldown.

The book drops from the general enchantment book pool, and the Enchantsmith applies and upgrades it at his stall in Wading Rainy Plains. Tier I costs 3 enchantment points plus 1 Echo Shard, Tier II costs 5 points plus 1 shard, and Tier III costs 7 points plus 1 shard, totaling 15 points and 3 shards for a maxed-out Thundering. Disenchanting is free and refunds the points, but not the Echo Shards.
