I’ve been reading a ton of DnD lately with Winter Fantasy last weekend. Let’s add a few things I think would be awesome.
Whirlwind Attack. When you would make a weapon attack, you can expend two superiority dice to attempt to simultaneously attack all creatures engaged with you. Each creature you are engaged with must attempt a Dexterity saving throw. On a failure the creature takes damage as if you had made a melee weapon attack plus extra damage equal to a number rolled on one of your superiority dice. You may attempt this any time you would make a melee weapon attack.
