Dark champions of Necropolis.

Hello everyone. Champions in the Necropolis are great, but if you're going to raise this new unit with necromancy (like a Nazgûl), the question is: how did the necromancer create two bodies from one dragon – the dragon itself and the rider on it? Besides, necromantic dragons in the original game aren't very impressive. My suggestion (unfortunately, I can't do it myself):
- Level 6: Death Knights
- Level 7: Banshees (Necropolis is about death, and death, as we know, is associated with a scythe – in my opinion, this is a clear symbol of the faction)
By the way, dragons (according to the description of bone dragons) don't live in the lands of necromancers, so why not make them neutral (but still allow them to be raised with necromancy)? That is, we swap the dragons and champions, remembering the levels (see above). And then we can adjust the Banshees – strengthen them (because they will then be one level higher – level 7). By the way, the action of the Temple of the Underworld now makes more sense – instead of turning everyone into dragons.
And another idea – since dragons fly, to maintain balance, we can make the undead teleport – they turn into a black cloud and disappear, then reappear (along with the cloud animation) at the destination.

I tested it – it's GREAT, but a 25% chance is too much – this ability needs to be removed. Also, the regular upgrade option says that the Sorcerer has 9 mana, but the spellbook doesn't open, i.e., either the mana and the Sorcerer ability should be removed, or he should be given a spell, otherwise, what's the point of the mana and the ability?
