Bink's Wrath of the Righteous OOC

[DarkOne-Rob]

Riftwarden Orphan (Archmage): The PC gains a +4
trait bonus on caster level checks to penetrate a demon’s
spell resistance. Once per day, he can recharge a charged
magic item by expending one use of mythic power. Doing
so adds a number of charges equal to 1d10 + his mythic
tier to the item, up to its normal maximum number
of charges. The PC will learn -spoilers, yo!-

Stolen Fury (Champion): The PC gains a +2 trait bonus
on Fortitude saves. By expending one use of mythic
power as a swift action, she can ignore a single demon’s
damage reduction for 1 minute, and increases the critical
multiplier of any weapon she wields against that demon
by 1. The PC will learn the true purpose of -spoilers, yo!-

So...I want the fluff for the Riftwarden Orphan trait, but the Champion Mythic Path. I wouldn't mind the mechanics of the Stolen Fury (eventually), but I don't mind the mechanics of the Riftwarden Orphan. Is there a reason to tie the Mythic Path to the trait? And what is this I hear about having a mix of two mythic paths?
