Hey, I would like to ask one more question (yeah, I know I'm third time in this topic in last week, but I tried to google it, but can't find the answer :D). If I want some challenger item as a wearable, but I want to summon challenger as well, I need to buy it twice? (simply: if I use item to unlock challenger, will it consume or stay in my inventory, so I can use it as wearable?)

yes, unlocking the challenger uses up the item.

ok, thanks for answer :( you can lock topic as well ^^
