So, the Arboreal Snags in the Dead Wood encounter have the Blood Roots variant ability, giving them regeneration 5 deactivated by positive damage. We’re only half way through the first book but reading ahead to this has me concerned, as (due to following the guidance in the players guide) my party are law abiding citizens of Geb with no access to positive damage, and I don’t see any reason why they’d pick it up by the time this encounter rolls around. Since they can’t be killed until regeneration is turned off, doesn’t that just make this an unbeatable, non-plot-relevant encounter? Has anyone else had this issue? Am I missing something, or am I best to just change that variant ability for a different one and be done with it?
