Ah. Good. Great. Then Skickpit is just an idiot who doesn't know anything about dwarves, one of the most common races in D&D history ever.
I suppose one can argue that he's a slave and is just desperate and using whatever he has at his disposal in the hopes of killing Magmar. I suppose one could assume that he's been poisoning Magmar little by little to soften up his constitution and now he's about to lay on the big stuff.
As I said above, perhaps it is just a matter of me being a DM. There's nothing worse than being a DM and playing D&D with a player who was/is a DM, always challenging you on everything.
