The Resonance Shield is activated by Xeno, who then deals damage to all foes on the battlefield equal to 225% of their Attack and returns 8% of the damage sustained to them. The Resonance Shield absorbs damage and provides immunity to most control effects for 3 seconds. (Total damage cannot be greater than 2000% of Xeno’s Attack) After Xeno utilizes her ultimate attack, she can’t use it again for three seconds.
When an allied hero’s HP falls below 30%, Xeno will send out her drone to save the ally by taking all of the damage the ally has taken, while also lowering the damage taken by 25% and reviving the ally’s HP to 35%. Xeno will turn off the drone support when the ally’s HP reaches 90%.
The three foes that are closest to the spawn place for allies take damage from Xeno equal to 225% of her Attack.
For each enemy hero who is still present on the battlefield, Xeno receives 1 stack of Nano Regeneration. Xeno receives 0.5% of her maximum HP in healing with each layer.
