Mel's wine does do more damage, as well as the enhance pot does help...
HAVING SAID THAT, it's like 5 hp's more for the enhance pot at 50%. To me, there is a better use for that jewelry then using those crappy rings. I'd rather have high DCI 1/3 with LRC or something then bother with 5 hp's more...
Mel's wine is more expensive to use as well, and only adds like 3-4 damage. I'd just use normal greater explodes.. I mean - when it boils down to it - you only REALLY use those pots in grinder situations to break another guild's grinder, orrrrr if you are house hiding *Cringes* And if you ARE house hiding, you don't deserve to get a kill anyways (completly besides the point haha).
