If you successfully hit someone with the Spear, Syringe, I a take it that an individual would take an addition 1d6 damage? would they roll to see if they were on fire next round?
But a syringe spear injects liquids, right? And there's no telling what alchemical fire does when it doesn't get exposed to air - it might be completely harmless.
Maybe. As an EMT,if you put anything into the bloodstream that doesn't belong there, it is usually very damaging.
