First Morostide I've taken part in. What is Morostide and how does it work? What about hexes?

there will be floating items around the site - click on them and you'll get them.. then you can 'carve' the 'uncarved pumpkin' that goes in your inventory and add it to your pumpkin collection (or sell it)... also, you can trick or treat, egg, or TP a person through their user profile - you might get 'tricked/hexed' if you ToT them, or you could get a 'treat/item'... also get achievements, and the pumpkin patch you go there too - basically just do what is in the news post and go on the morostide forum and participate...

You can hexed by going to TOT someone else? Can you cure yourself?

There is no cure for hexes, they wear off on their own after a little while.

But can you get them from toting someone else? What about TP and egging?

ToTing is the only way to get hexed.

Then what's the difference between ToTing and egging and TP?

ToT (Tiick or treat) either gets you a treat or a hex. Egging and TPing gets achievements for both you and your victim.

Different achievements.

ToTing is the only way to get certain items. Usually Morostide themed foods, but also stickers and some wearables. Here is a list of this years items

You get nothing from egging or TPing except achievements. Although there is a chance that you can get a or while doing them.

Also there is a Hex remover.

How long does it take for a hex to wear off then? And what are the chances of getting one?

Mine seem to be wearing off in about an hour. They are actually kind of fun in my opinion, I've been a chicker, a raven, and a giant oozy worm so far this year. It's totally random, chances seem to average that 20-30% of ToT's end up as a hex. The Token shop will likely start restocking Hypno-Monocles soon. They are supposed to cut down on the hexes so you get more goodies. I have yet to catch a restock on one yet tho.
