Jinx Witch - Jinx Feast

[Gruftzwerg]

Hi everyone, the time has come for my first "Full PF Ruling-Campaign" to play. So far we just included some PF material in our 3.x sessions, but now one of our DMs decided it would be a good time to give it a try to play a pure PF session. :smallsmile:

I decided to play a witch and stepped upon the "Jinx Witch" archetype. It looks quite nice but we (my DM & me) aren't sure how the "Jinx Feast" ability works.


(TL;DR) Questions:

1) Can the Jinx Witch use Jinx Feast multiple times?

2) If yes, what are the restrictions (beside those for spells not from the witch list)?
a) unlimited use SLA with no restriction (which would be totally OP and cheesy, but maybe it's RAW?^^)
b) unlimited use for up to 1h or until you expend the "eaten charge" by "casting" a spell. (this is my best bet for RAI)

For the sake of this discussion I would like to know your opinions, may it be RAW or RAI (would be nice if you would point it out).

A jinx witch can use the ability any number of times, so long as they have not run out of jinx-eating.
The spell lasts for 1 hour after being consumed, and once used is gone.
