One of my faves was reflect 100% on self for 1-2 seconds. It acted as a low cost, timed parry and was mega fun to fight mages with.
You can do the same with sanctuary, but any % of sanctuary is useful, and people really sleep on it imo.
ETA: Just remembered another old fave, very low damage fire damage on target, enchanted on something. Because there's no cooldown for the animation of casting from an enchanted item, it was basically a little flamethrower. I liked to put it on my gauntlet and feel like Boba Fett.
100% a placebo and bad habit so don't do this, but if it's a single bite I'll gently squeeze it like a pimple, and for some reason that tricks my monkey brain into thinking I did something about it.
Also that Dungeons And Dragons is the only role play game.
Oh man I could go on about this. I almost exclusively run Savage Worlds, and it straight up doesn't get enough love for how versatile it is vs. cramming a fistful of homebrewed rules into D&D.
To give my own examples: As a pixel artist it drives me nuts when people call anything pixel adjacent "sprite art", because a sprite is just any art made to represent an object/character in 2D, and can be pretty much any art style or even be a 3D model in some cases.
Similarly, the weird conflation people seem to have of voxel art with pixel art. They both have very different design principles, and turning pixel art 1:1 into voxel art doesn't often work as intended for either style.
