I'd say the 66 charisma jungle map. Drops 3x the bronze archer that gives bonus exp. regardless of class. Kinda like Hassim from the desert maps and the old bronze mage from the Magic City maps.

The new daily revival system will be implemented after this week's maintenance. The schedule so far is:
June 30th: Cloris
July 1st: Belinda
July 2nd: Azami
July 3rd: Momiji
First two I need for mincost and skill ups, last two are meh for me. If you are new to these events, you will get the first-time 100% drop. For others, the drop rate will be the same as usual. Seeing as we are getting farm event revivals (except for Cloris as her's is probably the urgent mission training stuff), we should be getting the event units themselves. Sweet.
