Heroes 5.5 - Tribes of the East - Academy Campaign Mission 2 - Impossible Difficulty

This mission is split into 2 parts, in the first part i play as Zehir and need to find 2 more priest to start a ritual, there is also a Tear of Asha artifact in the underground area, after i find all the priest and start the ritual a strong demon stack tries to stop me, when i conclude the ritual i meet Freyda and Duncan from the Hammers of Fate expansion, which i gain control of them and Zehir leaves. Freyda is gonna be one of the heroes for a mandatory miniboss fight in the final mission of this campaign, nothing much happens in this 2nd part, i build my army and fight the strong Inferno hero and destroy both Inferno towns to end this mission, in the meantime i try to build Freyda and make her ready for that important encounter, also luck on my side and got the Shield of Dwarven King artifact from the caravan, i cannot stress how much it helps in that fight, mainly because without it that enemy hero will just spam Frenzy on my units.
