For me, Deep Gnome is masterrace for pretty much anything fleshy. Reason for this is the permanent blur, color spray SLA and stoneskin SLA which is HUGE! Couple their proficiency with repeaters and to me its an instant win for artificer. Problem is, as an iconic class - they start off as a WIZ, which im not sure if thats a good thing for arti or not. Would it be possible to put together an effective deep gnome Arti/Wiz that uses repeaters or rune arm + blade barrier for AoEing? So Rune Arm or Repeater for single target and blade barrier to destroy mobs that are rounded up/chasing you down a corridor?
Or would bladeforged pal/arti work? What with the heals and all would this be better? Id be missing out on permanent blur and stoneskin, plus free SLA color spray as well as repeater innates.
