Aegis Protocol

You activate a predictive targeting system within your armor, creating a defensive perimeter around yourself. For the duration, when a creature enters your reach for the first time on a turn, you can use your Reaction to make one melee weapon attack against that creature.

The attack must use a weapon you are wielding or an integrated weapon of your Arcane Armor.

A creature triggers this effect only when it enters your reach as a result of its own movement. Teleportation, forced movement, or being moved by another creature does not trigger the effect.

Once a creature triggers this effect, it cannot trigger this effect again until the start of its next turn.
