That 99 Stamina really isn't a joke.If you want to clear it just for the stone, you should be aware that everything is massively buffed in there.Godspeed if you roll Seraphith as the floor 5 boss, he has 57M HP on top of his usual antics like resolve, 50% shield, etc.
Predras are the number one killer of 3P automatch partners in arena. Make sure at least one of your partners have a defense void, true damage, or way of guaranteeing a guard break activation before killing on the Chinese girl floor. This is especially important when you or any of your partners have less than tanky teams (<53k hp). I can't even count the number of people I've seen die to the predra floor because of this :c(pls)
Current OSC is actually OSC 18:http://puzzledragonx.com/en/mission.asp?m=3133The one listed on PADX is OSC 19:http://puzzledragonx.com/en/mission.asp?m=3168Was really confused when I entered and didn't see Lakshmi. Rewards are still the same.
[EDIT]*** CHECK COMMENTS More informed people have corrected me and given better tips.I know some folks are waiting until the patch to remove the +297 requirement, but if you already have them in your box then this is a good way to get more value out of it.
Lots of people are farming and skilling up Nazca for the Ganesha team. Mystic Dragon Historic Site (tech dungeon) has 20x plus-eggs today. I was collecting between 2 and 5 plus eggs per run, and 100% boss drops for skilling up Nazca - a decent bonus!
