The day they banned multi-use magic items was the day I became set for life. Not so much that potions became more powerful, they were still hard to use if you weren't casting on yourself, but suddenly they were the only option. People still wanted to set things on fire or freeze them in place, but were unwilling to spend the years studying how to do it without turning their brains inside out. So they had to take their chances with throwing small bottles of liquid.
So a guy like me, good at dodging thrown bottles? I'm set baby, totally.
