Hurls an fireball at the target that splits into several smaller ones, dealing Fire damage.
This Pyromancy could be used to kill efficiently a quite large amount of weak foes that are hunting the player down. However, the main focus of this spell is not to instantly kill targets but to hit as many targets as possible. As such, this can be quite useful for staggering groups of enemies that are chasing you down.
Bursting Fireball is a very situational spell in PvP. It can catch players as they are coming out of their rolls and also apply some pressure to gankers. Furthermore, Bursting Fireball has a shotgun effect where it deals greater damage if all the fire shards hit at close range. This pyromancy can be used to manipulate the battle field, forcing players to roll inwards or to the side (where you can have a Seething Chaos set up).
