Where is this displayed in-game?
It's in the How to Play Tab -> Gacha under the game.
Nutaku Gold can be used to draw:
Premium 10 Chain Gacha

Magic Jewels can be used to draw:
Magic Jewel 10 Chain Gacha

that will give you
at least one SR or higher Weapon or Eidolon guaranteed!
And it doesn't show when using jewels since there's no transaction notice but when using gold, it states it as well in the description when purchasing the 10draws.

A poor move by the devs IMO, notice needs to be placed on the gacha screen before purchase.
