I say 3 minutes, otherwise your event is gonna be painfully long.
Allow condensed red pots for lif <3 and other items needed for homun to cast their skills.
I would be against buffing food personally, use your natural stats and gears, not +stat food.
Perhaps allow white/blue pots for alchemist (50 white/5 blue), but not creator?
I would allow green, panacea, speed pots and converters, unlimited.
I say keep restrictions to a minimum as well, not just for the player that has to remember it, but for the GM that has to be checking the fight and monitoring 2 players at once.
