Wasn't able to find an answer, but what's to prevent a PC from burning XP to create a Huge Number of scrolls and casting them ad nauseum during combat? Any GMs had this problem with their players?
Hi!
What's the problem?
Ad 1: Who allowed the player to take the relevant feat? Prevention is everything.

Ad 1.1: If the player in question can be argued with, change/retrain the feat.
Ad 1.2: If the player in question can't be argued with, arrange for a "prolongued holiday on Tarterus". And don't allow the feat again or any other item creation feat.
Ad 2: There are some more factors to calculate in:
Ad 2.1: XP, as you mentioned (limited to the border of level loss),
Ad 2.2: Money (limited to the funds a PC can lay hands on),
Ad 2.3: Time (limited as the DM sees fit).
Ad 3: There are some technical factors to concern:
Ad 3.1: Fetching a scroll during combat provokes an AoO,
Ad 3.2: Casting a spell from a scroll provokes an AoO,
Ad 3.3: Scrolls can be burned, sundered, disarmed, stolen, etc.
Ad 4: Miscellaneous:
Ad 4.1: What's the difference of having a spell-slinger casting spells from "within" or from a scroll? He/she/it can't cast more spells in a round than usual.
Ad 4.2: Waste management will seek him out for leaving a trail of litter behind the encounter scene...
Kind regards
