Deus Ex Machina

 Call upon the power of Deus Ex Machina :

{Grants the ability to summon a indestructible, god-like construct forged by the cosmos themselves at an cost.}

 "Oh I grant thee a gift forged by those beyond perception, I grant thee salvation, make it but bare the consequences."

{The dungeon master saves the party with the power of this infallible gift, oh how kind, but with some caveats like a feat refresh quest or/and a reality altering challenge.}
