I liked the djinn idea someone mentioned and I like the concept of Weave Self, so I would do some sort of attunement count, once you reach x attunement changes, you gain access to f5, f5 transforms you in a djinn based on the attunement you were in (massive damage, support, heal). Change either the conjures or signet into wards (unstrippable effects)Examples (temporary names):Ward of Taimi - while in this ward foes move 33% slower.Ward of broken dodge key - while in this ward foes are exhausted and endurance gain skills don't workWard of slow - while in this ward foes attack and cast 50% slower.Ward of no F skills - while in this ward foes can't activate F skills. Edit: For reference: https://wiki.guildwars.com/wiki/Ward_spell Something like that I guess.
