Add WSS to Bee wing!

[Merellis]

Just go hunt them then. Bathory is an excellent card to hunt and Demon Pungus drop them at 100%, along with Yellow Gemstones that Prof's love, Hodremlins give decent exp for a Sin and also drop slotted Boots and Shadow Walks, along with a very awesome Hodremlin card.

There, multiple ways to gain WSS as well as other items at the same time.

If you don't like the price, then get it for nothing instead.
