Alternate Solution
It never fails for rogues. They search the floor. They search the doorway. They search the chest. Each time they get a super high number but find no traps. But the one time they roll a “3”, that will be the trapped corridor. The one time they get distracted and forget to check a doorknob, that will be the one with a horrible player killer defence.
“did you check the corridor?”
“Yup. Clear.”
“Hmm… let’s send in the barbarian first. Hey, Brutus, look, is that a cask of ale down there?”
Unrelated food for thought regarding Damage Types in D&D. Dunno what or even if you want to do anything with it.
1. So, D&D, and several video games I’ve played (namely Warframe), split physical damage into three different categories; Bludgeoning, Piercing, and Slashing. While this makes sense from a weapon categorization stand point, anyone with any basic knowledge about how Medicine categorizes injuries knows that physical injuries are split between blunt-force trauma and puncture-force trauma, where lacerations (slashes) are a subcategory of puncture-force trauma.
2.In D&D Angels are resistant to Radiant damage. That makes sense on technical level, but not traditional lore-wise. Traditionally, the only beings capable of consistently harming Angels are other Angels.
