I reskin almost all my spells per individual character and its a lot of fun

By reskinning i mean that I describe the spells in a specific way, the mechanics of the spell will be what is written.

I had a blaster half-elf and all his damage spells were a variation of him creating a magic bow into his hands and releasing an glowing arrow of different types.

Fireball? Flaming arrow that explodes on contact.

Ray of frost? He conjures an ice arrow

Scorching ray shoots three arrows in a quick succession.

Etc etc.

I've had dwarven wizards that prepared their spells by writing dwarven runes in their armor and weapons.

Reskinning spells is always a lot of fun
