Starling can cast the following:
Crying mask // Candles * // Day of the Dead set

The Halloween sets can be seen in Keepiru's "A Complete Guide of all TEF Sets"
*Candles can only be cast onto bare / default antlers, so make sure you sneeze them off!

If you would like any set pieces, approach Starling in the forest & tap the ground/lead us to some spell trees, etc.
