Planar Champion

Warriors of a hundred worlds, mercenary captain of the Blood War, sword of celestial vengeance. The Planar Champion moves between the planes, always driven to battle. She may be driven by a quest for justice or a thirst for blood, but she is feared throughout the known multiverse for her prowess. All Planar Champions were renowned for their martial prowess before they entered the prestige class, so those classes skilled with weapons gravitate to this class. They specialize in fighting the natives of particular planes, learning as much as they can about their foes in order to defeat them.

Planar Survival
The Planar Champion has adapted and is not subject to the natural hazards of the plane he's on, such as the fires of the elemental plane of fire, the diseases and apathy of Hades, the acidic rain of Gehenna, the carelessness of Elysium, etc. He is still subject to any other fire damage, diseases, acid damage, and so on.

The Planar Champion has studied the natives of a particular planar region extensively. Twice per day the Planar Champion may receive a +3 weapon enchantment when fighting inner-planar creatures (elementals and their kin) or ethereal creatures or creatures whose essence is of negative energy (undead) and a 1d8 damage bonus against them, as well as a +3 affinity check to all skill rolls concerning such creatures and their environment [Works at DM discretion].

Once per day, a planar champion can rip a temporary portal through the Astral to another plane of existence. This functions as a Plane Shift spell.

Scramble Portal
