Surcharge

Slug: spell-cast-fire-surcharge
Description: Burn all enemies in a wide zone, detonating those already ablaze
School: Fire
Element: Cactus
Level: 12
Cooldown: 60
Cast Delay: 0
XP Multiplier: 0.75
Overview: Burns everything in a zone - and if any of them were already on fire, they detonate. Surcharge is the Pyro school's combo detonator: cast it after Fireball, Wisp, or Firebeam have applied Burning and you turn the DoT stacks into instant burst damage across the entire group.
Strategy: Always pair with a Burning setup spell. Fireball into Surcharge is the classic, but Wisp spreading Burning to a group before you Surcharge is often more efficient. The wider your Burning coverage when Surcharge lands, the more simultaneous detonations you get.
Pros: Detonates Burning enemies for immediate burst damage Wide zone means it catches groups rather than single targets Multiplies the value of every other Pyro spell significantly
Cons: Does ordinary burn damage against enemies not already on fire Requires setup - useless as an opener
