Hello,

in patch notes I see this:

"You can exchange Tuvala Awakening Weapons of other classes for the Tuvala Pendant as a season Maegu with the Tuvala Awakening Weapon Exchange Coupon."

Which makes me think it should already be possible to exchange the Woosa pendant/placeholder to the Maegu pendant/placeholder. However, I get an error when I try to do that. Anyone else have this problem?

"The Weapon exchange coupon cannot be used on this character.", is the message I get.

Had the same problem converting my PEN Woosa pendant into Maegu pendant. 

So, after doing Maegu succession quest, I got her PRI pendant and was faced with the annoying ordeal of making another Pen pendant (since only one set of tuvala can be converted for normal server usage), then I tried the coupon again on Woosa's pendant and it worked.

So they either they fixed the issue or you need to complete Maegu's succession quest before attempting the conversion.
