Focusing all your resolve, you stand fast and watch your enemies flail against your defenses. As a Magic action, you become motionless and gain the following effects:

• You have a +4 bonus to AC.
• You have Disadvantage on Dexterity saving throws.
• You have Advantage on Strength and Constitution saving throws.
• Your Speed is 0 and you can't benefit from any bonus to your Speed.
• You lose Concentration.

You can't take actions, and you can't use your Bonus Action except to end the effect of this trait.
