Why not have stances for DnD?

Mountain Stance

prerequisite: monk unarmed attack feature

No force can move you! As an bonus action, you can enter the stance of the mountain. You can only be in one stance at a time When you do, gain the following benefits:

• Gain advantage on any saves to remain where you are, remain stationary, and remain upright. Enemies gain disadvantage on any attempts via attacks, spells, or abilities to remove you or knock you down.
• When you are upright and have both feet on the ground, one attack you make each round gains bonus damage equal to 1/2 your level, rounded down.
