3rd job advancement questions

3. One ETC slot for the Proof of a Hero, which shows you killed the clone.

You need to loot the Dark Charm the clone drops first o.O (unless that's what you meant Greg)

And if I understand the coding of MapleStory's quest systems and such, you actually need two ETC slots devoted to the job advance. You exchange the Dark Charm for the Necklace of Strength btw xD

And then there's the Dark Crystal, the Necklace of Wisdom...

You only need two ETC slots at most, and have a Dark Crystal ready somewhere xD
