How to Save Blademaster Harboym in CH3

[chessplayer]

It is one sorcerer and some ninjas. I cant seem to win even if i equip only my team with short bow. I never can even make it to the leader before he dies. I heard that you can throw stones at him to make him retreat, is this true? How can I make that guy retreat before he gets killed?

I use 2 clerics and constanly heal him too.

what should I do. I am level 20.

Please give me some pointers. thanks

Throwing stones is a good idea. Have your guys focus on one enemy at a time or the enemy that Harboym is attacking. You should not finish the mission until he is saved. You can also level up your troops in training to make them a bit more powerful. I recommend using ninjas/agility characters and having everyone focus on getting as close to him as possible. You really want to surround him and take some of the attacks.
