Artillery Barrage

As an Artillerist, your job is to bring the pain in the form of direct fire on anything the appears before your eyes.

Starting at Level 3 while using the Arcane Assault Suit, conjure a Multiple Launch Rocket System onto your back. Fire fire  arcane rockets at up to 3 different targets, for every artificer level you gain an additional rocket. Each rocket explodes for 2d10 Fire damage in a 5ft radius in addition to the target being set on fire (the burn damage stays the same regardless if one or all rockets hit 1 target) on a successful hit. The damage to the target is halved and not set on fire if it makes a successful Dexterity save.
