Crimson Longinus
Legend
This again seems to indicate the level of dissatisfaction with the game than will realistically never be addressed. So perhaps stop being mad about it and go find a game better suited your tastes?Stopping spells with magic swords and armor is a pretty bog standard fantasy tropes. That's some level 5 appropriate stuff IMO (expend reaction, gain advantage on save). Far more so than casters flinging spells in a single round, which is a trope of D&D, and... like nothing else. Hell, even D&D novels don't have the heroes casting spells much, probably because the writers realize how lame it is. .
Simply don't level yours up if you want to remain a wand caddy for the real heroes.
