[early dracoshield]

I have just started playing Shadows of Valentia and have used the DLC to get my units (aside from Alm)  to their second tier classes (Gray- Myrmidon, Tobin- Sage, Clive- paladin, Python/Kliff- Sniper, Faye/Silque- Saint, Lukas/Forsythe- Knight, Clair- Falcon Knight) and want to know what levels I should be before trying to get the Dracoshield in act 1?

I just noticed, it's Alberia from fe1 etc that's west of faerghus, not Albenia.
