Pulsars are enemies summoned during the fight with Astellarn. They attack every player in the arena with dwarf multicannon (typeless) damage that increases with the number of players in the arena.
Leaving two alive and killing Astellarn is a requirement for the A Quest for Understanding achievement. In solo, it does 900 damage max, in duo 1,800 damage, in trio 2,700 damage.
In Story mode its health is reduced by 50% and its damage output is reduced by 90%.
