If (in my event, not speaking for other GMs) I'm allowing healing items, I'm only allowing blue pot, green pot, white pot or condensed white pot. If you want to win a pvp tourney for pride/glory and good items, you better pay your effort and buy/brew your stuff.
No fish is definite. You can't change me on that one (but seems like everyone so far agrees anyway.)
Great job on different opinions and making precise constructive ideas so far everyone keep the ideas coming~
