You think AOE DPR will be low? Have you ever played with a Tempest and/or Light Cleric?
The Light Cleric will be Dex based so half the party will be stealthy, and the other half will be clanky. Isn't that at least almost normal for a party? Maybe 2/3 Dex, 1/3 Str on average.
I'll throw them some bones, but I want to be hard on them. This is a one(or two) shot after all. Like I said in the beginning, they're being smarta**es by choosing this party. It's almost like a dare to throw everything I have at them. These guys have been playing with me for too long lol
