Worshipper – “Agral’s Decision” [Campaign 2, Mission 5]

Wow, how do so many people get such large groups of dragons to appear before the bridge?

And here's how! The second time, I had 59 of them instead of 35! But I successfully defeated them all without much difficulty by creating succubus phantoms. This time, I only started gaining experience towards the end of the Campaign; before that, I only took gold from the very beginning. By the way, as a bonus at the beginning of the game, I decided to take the succubus sisters instead of the sextant – I didn't move as slowly as I could have.
In the previous "Ship" Campaign, I played it to the maximum, defeating everyone who didn't want to join in order to raise Agrael's level to the maximum – I brought him to level 30. I didn't get any "babes" or "dragons," as many people wrote here; I probably didn't learn the "Suggestion" spell because I only studied elven magic in all the cities, and no one offered "Ur-Gash's Call" in the demon castle, even after sacrificing all the demon creatures. My army consisted only of units from the elven cities; when I saw that they started to run away over time, I hired an elven hero, whom I used in the previous Campaign, and took him with me everywhere – no one ran away from him; we switched "armies" for the duration of the battle (I gave him a couple of demonoids). If I left the army with Agrael, even for just one night, a couple of elven units would always run away...

Now I want to ask, has anyone raised Agrael above level 30? Are there any? What is the maximum level he could be raised to?
By the way, I probably wasn't studying elven magic for nothing, because Tieru cleansed Agrael for subsequent missions in the name of good, if I understand correctly? Where will Agrael appear in the future?
Now I've started the Necropolis Campaign with Marvel.
