From the last SK stream I think they wanted suggestions on how to improve the sovereigns ability so it is a no-brainer choosing this. Tyrant has coercion, which I think is a very nice ability.
I think the Hypnotism is ok, but maybe it could be switched with some kind of scrying pool-building. After all he is the Wizard, he should probably know how to channel some of the essence/mana/power from other cities to this one city with the scrying pool.
The skill tree could include:
- spell books with more advanced spells not otherwise available for the other sovereigns
- a summoning path focusing on summoning
- skills to improve casting e.g. reduced casting time, reduced casting cost, more spells per combat (+2 instead of +1), and this branch could also be capped off with the BIG ASS Counterspell
- maybe a necromantic path (if there is room available) with better skeletons, zombies, ghouls, liches, vampires ( and maybe werewolfes too), able to raise dead units right after the battle and even slain heroes, however they would have the tag Undead.
