Mythic Deathless spell Question

[Tom Marlow]

If you cast the spell Deathless (http://www.d20pfsrd.com/mythic/mythic-magic/mythic-spells/deathless) augmented 8th and are killed via power word kill. Would your allies still benefit from it or (since you are dead dead) would be out of luck?

[GM Rednal]

In general, a spell that's been cast will continue until its duration expires, regardless of whether the caster is alive or not. So, yes, your allies would still benefit from it.
