Scrapping with the Shamos

This one is pretty easy, kill 13 little Shamos and gather some tickets. This gives you the Sealed Eyepatch. Nothing special other than its a limited time item you'll eventually be able to wear as a vanity item. It gives Level 1 Fire Resistance.

Wicked Wildspire Warfare

Hunt Diablos + 2 Baroth HR 8 or higher

This one might not be as easy, but its a good way to farm Armor Spheres if you need those. Can never really have enough, but better ones do drop later in the game.

Remember, if you dont participate, all events return during the seasonal festivals. Halloween Festival is right around the corner too.
