do I need to train the fodder before I eat them?You need to fuse some fodder heroes in order to upgrade your main ones and eventually evolve them to 5*s. The higher the level of the hero you fuse, the higher the training percentage goes up. You need to get it up to 100% and get your hero to max level in order to upgrade him/her.
It's not so bad. Just concentrate on evolving your Valiant (Freya) like Bunny suggested. She's a great damage dealer and will carry you through the early stages just fine. Teresa is a good healer too. You have the best Faiths for her so that's a good thing. People tend to go the Archbishop/Inquisitor route for her. I personally think you should go Magebane for Kai since he's a Kensei already. AOE Silence is pretty useful both in PVE and PVP. Assassin Kai has turn refresh but it's not that crucial IMO.
I also didn't have any ranged units in my noob days. I got some crappy pulls too. But have faith in RNGesus, for It will give you salvation... Eventually. Kidding aside, just try to enjoy what you have. You'll get better as you progress.
As for 4*, it depends on your squad comp and their skills/auras. Most use them for training fodder though. But some are useful in the beginning.
Thank you, I got another kai (atk faith) and finally my first mage Zed( atk faith...), now what path to go ?
what does that mean use 4* for training fodder?
and how to unlock legendary map?
Training costs gold. Lots of it. So in order to economize, you need to sacrifice those 3/4*s to develop your main team while saving gold.
You unlock the Legendary stages by completing all the heroic stages which are, in turn, unlocked by completing the normal stages. Build up your team first. Don't rush mate. Enjoy the ride.
then what to do with 1* 2*?
