I was plotting the end of my heroes when I found something interesting.
Point one: In this final reinforcements come in the shape of master monsters from four groups, aside from cave spiders who come with three minion spiders.
Point two: each monster group are given element stones that give them a special boost.
Point three: after reading what each element stone does, quest rules read: "Each monster also gains the ability that matches the color of the objective token (element stones) on their corresponding monster card, with the exception of minion cave spiders."
My question lays with my "Reinforce" overlord card. If I reinforce a group, except cave spiders, to have minions (because the game does not give them to you in this final), will those minion monsters gain the abilities of the element stones?
