Bracing

You can brace yourself using surfaces or objects in your immediate vicinity by spending an amount of movement equal to half your speed. When you do so, you are braced until the start of your next turn: your speed is 0 feet, and you have advantage on ability checks and saving throws you make to avoid being moved against your will. This condition ends when you move away from the surface or object you used to brace yourself, or when you become incapacitated. You can brace yourself on a creature at least two sizes larger than you, or any creature with the Kaiju subtype. If you are braced on a creature, the first attack roll you make against that creature before the start of your next turn has advantage.
