However, this is contrary to both B/X and LL. Was this an oversight or a deliberate change to make green slime less lethal?
I encountered this in Beneath Brymassen last night with my 2 boys. Since they didn't really know to use fire, and the rulebook didn't say otherwise, they shot an arrow at it and killed it. Didn't make much sense to me, but I also didn't feel like killing anyone with green slime.
