While the barrier is active, incoming bullets have a chance to be deflected back toward the attacker.
The barrier does not benefit from resistances.

Rule, Rattania!
Rat King charges up and summons the banner of Rattania.
All nearby allies gain increased movement speed, immunity to slows and reduced incoming damage while they remain close to the banner.
The banner grants:
- +3 m/s Movement Speed
- Movement Speed Spirit Scaling: 0.05
- 20% Damage Reduction
- 24m Radius

When Rat King slams the banner into the ground, the sewers beneath it violently erupt.

Rat King's playstyle
Rat King's abilities revolve around staying in the middle of fights and overwhelming enemies with several layers of pressure.
Scrap Grenade gives him repeated area damage and a slow, while Rat Swarm can continuously pressure individual targets and reduce their Bullet Resist.
Royal Pestments gives him extra durability and a chance to return incoming bullets, allowing him to survive longer while pushing forward.
Finally, Rule, Rattania! combines team utility with a large area attack, granting nearby allies movement speed, slow immunity and damage reduction while also damaging, knocking up and slowing enemies.
The ultimate can additionally spread Rat Swarm to enemies caught in its area, tying the rest of Rat King's kit together.
