I consider it fair play and good DMing to describe damage resistance after a PC hits a creature resistant to the attack's damage type. Lately I've been feeling like my descriptions are kinda lame, mostly after hearing similar statements from the mouth of a talented DM (Matt Mercer on Critical Role). "You punch the creature, but you don't feel like the punch goes all the way through," or, "The attack doesn't do as much damage as you expected." It feels vague and flat, but I have trouble imagining more descriptive reactions to resisted damage types.
Two complicating factors... First, it doesn't make sense to use the same description for different creatures. For instance, a Will-o-Wisp resists weapon damage differently than a Grick. Second, PCs don't necessarily have a reference point to realize their attacks are less effective for creatures they've never fought before.
Regardless, the pragmatist in me thinks I might as well just say, "You sense it has resistance to that type of damage," rather than clumsily skirt around the information I'm trying to communicate, and let the players interpret the info with whatever narrative suits their imagination. It'd certainly save me some mental overhead.
How about you? Assuming you telegraph damage resistance, what are some of the more immersive and sensible descriptions you've used for various damage types? If you don't communicate resistance, circumstantially or generally, why?
