Abilities 6 of Fiend: Marauder
Melee
You trigger a Melee ability by attacking the intended target with a melee Weapon or Unarmed Attack. If you do not have the Proficiency to use the Weapon, it is Ruined, or the arm wielding it is Maimed, you cannot use the ability.
Frenzy
You attack the closest valid target, even if that character is an ally, and continue to do so until subdued or Roused. A valid target is a target you are both aware of and can attack effectively. This is an exception to the rule that cooperative players may not be attacked by other players. Because you are compelled to attack the closest valid target, Soothe and Taunt will only alter your target if multiple characters are equally close to you.
Burst
A Burst ability includes the "Burst" prefix as part of the tagline and affects all characters close enough to hit or be hit by you in melee at the time it is called. The ability cannot be avoided or blocked, though countering and immunity apply normally. If the effect is detrimental, everyone in range takes the affect regardless if they are flagged for PvP or not. If the effect is beneficial, you may choose to affect yourself as well.
