What you will need: A shitload of priests
With Valentine's Day coming up, I'm betting a lot of you want to stock up on items that cause a 1 hour debuff (like misteltoe during christmas or trick or treat during halloween). Here's a way around the 1 hour debuff.
Get a bunch of priests together, and have t hem start casting mind vision on one person. Keep it up until the debuffs are stacked completely, and a new mind vision won't apply. Mind vision has a high priority on debuffs, and won't be overrode by the 1 hour debuffs.
Now, just go spam getting the item you want (mistletoe, candy, whatever).
