How to get UR Deep Sea King?

Good unit, recommended to get. It’s one of those units where you can get decent value out of it just by placing him in your line-up and it will help a lot. In this case, you get Encourage, S.Dmg Reflect and good DPS. AWK1 is not needed as well.

Pros of UR Deep Sea King

• Very versatile and strong DPS + a little bit of support

• Deals very high damage

• Provides Encourage (extra energy)

• Provides Specialized DMG reflect to all allies

• Doesn’t require AWK1 or KS so rather cheap

• Good DPS if you can put Cruel on Monster side and he can ult twice!

• It’s the only Encourage unit for Monster side if I’m not wrong, so it’s a strong addition for the Monster side, or fights with multiple line-ups

Cons of UR Deep Sea King

• Only deals max damage with 6 enemies alive (due to the multiplier). Hence damage will drop off as the number of enemies slowly die

• Due to the above, he is not good for bossing since there is only 1 unit

• Requires Crit gear if you want to build him for maximum DPS

• Need to save BT for upcoming units (Fubuki, DK, CK..)
