Underlord

Calls down waves of fire that damage enemy units in the target area, burning for additional damage over time.

A deadly pit is conjured at the target location; any unit that enters will be damaged and rooted. Each enemy unit within the pit are affected by the root only every 3.6 seconds.

Nearby enemy units are weakened, losing a portion of their base damage. If an enemy dies while under this effect, Underlord gains temporary bonus damage.

After an allied hero Teleports, they temporarily gain Damage Reduction and Movement Speed. Allies receive 2x bonuses if teleporting via Fiend's Gate.

Opens 2 portals, one next to Underlord and one in the target location. Heroes can channel a portal for 3.5 seconds to teleport to the other side. Portals have to be at least 1500 away from each other.
