Underground Treasure Hunt Day 2 Best Team
Sushang	Hook	Silver Wolf	Luocha

Sushang and Silver Wolf are the trial characters for the Ruin 2 stage. Silver Wolf is capable of adding another weakness type to the enemy which will aid Sushang and Hook defeat the enemies with ease.

Luocha can be exchanged with Natasha but he is best within the ruins due to his healing skill counted as a follow-up attack.

Note that you can find Hook by chance within the levels of the stage. You can bring Sampo or Dan Heng at the start instead if you don't have Hook or if you haven't built her!
