No.Is Nature Cleric's Dampen Elements ability way overpowered?
it should happen more often just because you are playing a Nature Cleric.
When players choose their characters, they are often asking you to feature certain things in the game. For example, when someone makes a trap focused rogue they are asking for some badass scenes where they disable traps. That doesn’t mean every place has to have traps, but it’s directly telling you, the DM, “Please sir, I would like to beat traps.”I would not, under any circumstances, rewrite an adventure just to squeeze in more elemental damage because someone happened to be playing a nature cleric.
