Chain Lightning
Thor's bolt arcs through every Lightning and + Healing block on your grid before it lands on the foe. Each Lightning block it touches adds to the damage, and the bolt scours freeze, ignite and curse off whatever it passes through. Each Healing block heals you and adds to the hit as well.
In detail
Thor's Ability deals 60 damage per Lightning block on the grid. Thunderstone, the tier-4 relic that drops from Echo Thor, casts the same spell at 50 per block. The bolt counts Lightning blocks that are frozen, ignited or cursed, and strips those statuses as it passes through them. Targets are struck in order of distance from where the bolt starts. Healing blocks on the path contribute half their usual heal. With no Lightning and no healing blocks on the grid, the cast is refunded.
