Feather

Feathers are fictional compo items enabling the characters to either revive themselves instantly (via the Light Feather), or kill enemies in a single strike (via the Dark Feather).

If the effect is successful, either of them will create "particles" that don't cause any damage (aesthetic purposes only), depending on the level of said feather.

These kind of compo items are sold for very high price of 1500 gold/level (level 1 is bought just for 10000 gold).
