Two super long challenges! Are you ready for 69 floor dungeon?

Challenge #1: Ultimate Arena 1-3!

• Three easier arenas back-to-back! 
• 99 stamina, 69 battles
• One clear only
• Reward for clear: Latent TAMADRA (Extra Slot) x 5

Good luck and hope you have Fujin-type actives handy, and be prepared to play some games with multiple Lakshmi.

Challenge #2: Ultimate Arena 4 & 5

• 99 stamina, 45 battles
• One clear only
• Rewards Jewel of 5 Great Dragon Generals , which is evolution material for Red Sonia . So far the only other place that gives this as reward is clearing Story Dungeon (first clear only).
