i was looking at them, mostly because of vitality which i was thinking was the scroll to increase your hp which i desperately need in KQ's but then i remembered that somebody before had said that they bought one but couldn't use it. i also noticed that one of them was nature's protection, the skill i had just gotten so i figured there must be other requirements that they're not showing. so i guess my question is what are those requirements if you know them? i figured the class requirements on the top 2 rows (pretty sure hawk archers aren't supposed to learn revive lol). but for the things like the production skills (hp regen potions, elrue tier 3 etc.) how much xp (production) would you need before you can use them. they don't even show up on the list in the skill window so something in the thousands maybe?
