A wicked grin exposed Solstafir's teeth when the elven zombie delivered a powerful strike on thr zombie minion with its bare fist, the enhanced chitin cracking and groaning under the impact. "Looks like this one might give us a workout!" Harpoon abandoned, he joined the fray and swung his ax with boundless energy in a wide arc to chop through any defense it might encounter, be it natural or supernatural. Once the dwarf occupied the vampire's focus his undead minion surged into its space to force it to the ground with its raw bulk the moment before Solstafir set up his strike.
