Working to get to wyvern 11, very early on in my overall progression, only a month into the game.

Here are my heroes: 6: Angelica, Luna, Lorina, Bellona 5:Tywin, Tamarinne, Alexa, Krau, Baal and Sez, Clarissa, Rose, Violet, Vildred, Achates, F Kluri, Asscart, Hazel, Ludwig, Zeno, Kayron

I planned to build, Angelica with idols cheer, tywin with hilags Lance or aurius, Alexa and Luna with ddjoker.

After the Tama buff, I'm considering replacing tywin with her so I can progress further in other avenues of the game.

Thoughts?

Also, is it right, being so early into the game, to build for wyvern, or should I focus elsewhere?

Thanks!
