this thread could be helpful: Best 3* heroes?
it really depends on who else you have… I would personally make two “rainbow” teams of heroes though.
- Red: Hawkmoon (because there are few good healers among 3*s), Namahage (fast and skill greatly increases attack). Nashgar, Azar and Jahangir are also decent.
- Yellow: Bane (one of the best 3* because fast/good skill), Melia (Fast, hits all, skill helps with tile damage). Gan Ju and Kailani are solid choices depending on situation.
- Green: Belith (heal + dispel, like mini Melendor or Sabina); Mnesseus (one of the best 3* because fast/good skill) OR Brienne (great, unique skill that’s great for offense). Berden is also good.
- Blue: Valen (one of the best 3* because fast/good skill). Gunnar for defense, Ulmer for offense. Have not tried Gato but seems OK.
- Purple: Balthazar (one of the best 3* because fast/good skill), Chochin (also a great skill). Gill-Ra or Tyrum are also good choices.
