I love this stuff - myths and fairy tales don’t seem intent on giving the protagonist a balanced challenge, it is rather about having the tools to overcome it. If a player can completely short-circuit an encounter, awesome.
My personal favorite, from Scion: We’re about to enter the Labyrinth on Crete, and some us feel uncertain about navigating it. That’s when one player says ”I have the Ariadne’s Thread artifact, that should work, right?” (She had bought it at chargen and never used it yet.)
(Similarly, my character could summon a bunch of Spartans, so when we were attacked by Persian Immortals…)
