Kind of a Niche kink but would love to see a muscle expansion potion. I understand it's not a kink many like.
But since there is a Blueberry potion then maybe there is a chance for some muscles? I don't really know how getting physically stronger would impair the adventurers fighting.
But maybe the muscle potion causes the adventurer to go berserk and lose self control making it easy for ghost monsters to possess the adventurer and use them for the monsters advantage?
Or there could be an Iron golem boss that is super powerful and wants to fight a worthy challenger?
Or maybe the muscle potion makes the adventurer into a simple minded brute of an amazonian making it easy for an intelligent monster like a psion or mindflayer to place them under their control with psychic power.
Love the warrior adventures in this game. They have great muscles. All good if it's a no on the muscle/rage potions. like I said not many like that expansion kink.
