The terror demon is a deadly creature formed from the essence of nightmares, constantly warping and adapting to its opponent’s weaknesses.
Using this warp on your head enhances your Living Nightmare power, allowing you to add your rank in Demon Form when determining whether the fear succeeds.
Using this warp on your skin increases both the physical and energy armour of your Protean Nemesis power by 1% per rank.
Using this warp on your arms causes them to transform into clubs, spikes or blades. You may alternate freely between the three combat tables, although each is only capable of inflicting a single damage type. If you have the Demon Spawn talent, then each rank in Protean Nemesis will give your arms a 5% chance of inflicting an elemental burst on a critical hit. The type of burst will be based on the energy mode of your Protean Nemesis power.
Using this warp on your Inferno makes it inflict Protean Nemesis energy damage.
In human form you may use this knowledge for Ritual Scarring. Placed on your wrists or ankles, this scar increases the bypass of your Protean Nemesis by +2 physical or +1 energy per rank respectively. Placed on your chest or stomach, this scar increases the armour of your Protean Nemesis by +4% physical and +2% energy per rank respectively. Placed on your head, this scar gives the same benefits as described for the head warp, except based on your Ritual Scarring.
