As previously mentioned, this dungeon will have a cost restriction of 12 such that none of your monsters or your friend leader can have a cost over 12.

From the terrific Pazdra Box blog here are some rumored dungeon stats for this one, coming on 7/15. Based on the info there will be a 30 stamina and 50 stamina dungeon (just like Dorarin), and it will be 5 battles each. Not clear here what floors 1-4 will have, but here are the rumored boss battle stats.

50 Stamina Version:
Tengu – HP 1078542, ATK 7944, DEF 0, Attacks every 2 turns
Skills:
Baku! – Incapacitate 3 members for 3 turns (used only once when over 40% HP)
Kai! – Hit for 11916, 60% probability of being used when HP is over 40%)
Metsu! – Hits for 5561 Damage and turns one color orb into garbage (24% probability when HP is over 40%)
Seishin o togisumashite iru – Not sure on this one, says that it will always be called when HP goes below 40% and probably immediately proceeds the attack below
Shojahitsumetsu – 63552 Multi-hit attack (attack when below 40%, probably follows the one above)

30 Stamina Version:
Tengu – HP 578098, ATK 4258, DEF 0, Attacks every 2 turns
Skills:
Baku! – Incapacitate 3 members for 3 turns (used only once when over 40% HP)
Kai! – Hit for 6387, 60% probability of being used when HP is over 40%)
Metsu! – Hits for 2981 Damage and turns one color orb into garbage (24% probability when HP is over 40%)
Seishin o togisumashite iru – Not sure on this one, says that it will always be called when HP goes below 40% and probably immediately proceeds the attack below
Shojahitsumetsu – 34064 Multi-hit attack (attack when below 40%, probably follows the one above)

So it seems like possibly when he goes below 40% there will be a similar automatic high damage attack thereafter maybe similar to Bahamut from CD?
