Destroy Equipped Item 3 times - I'm too lazy to change into low-level armor, so I always do any random Ein Lacher battle for this. The bosses hit really hard & armor breaks quickly, but there's no repair costs & there's unlimited revives.
I got a Makeup Coupon and an Appearance Alteration Coupon that I had been planning to buy anyway, which reduced the cost. Some of the other stuff was also useful like a couple of fusion runes and party graces.
I hate gambling & I dislike gambling boxes & I didn't want to buy them. But the pets are so adorable and I didn't have 100M gold to buy one from the marketplace.
I just wish Tir coins were available so those who hate gambling had a legal way to buy gold & then buy the pets from the marketplace.
