Elven islands - is my hero too weak?

[splattergirl]

thanks for the advice! which unit would you propose specifically? evil beholders were ok but there were few left to hire for example...



latest version, a bit more mana, int and rage (I can finally use the best Reaper ability), second rank of higher magic...
unable to beat necro castle, didn't find anywhere spells like Fire Rain
also, no black or red dragons I could hire, one egg with one dragon means nothing
