how would that make any sense fluf wise? kroak taught all the slann every thing they know. if they can do it then he should (and does) do it better he has always been slann+ and the only slann that varied in all of warhammer history are other named slann.
Take a look at Kairos and how he compares to a regular lord of change.
The difference between those two is:
- Kairos has 3 spells v.s. a LoC 2.
- Kairos has a different unique spell that can summon a spawn but degrades & does more reliable damage v.s. a less reliable damage spell but with higher maximum output and it doesn't degrade as the LoC gets wounded..
- Kairos has Oracle of Eternity v.s. a LoC beacon of sorcery
- Kairos knows all spells of friendly wizards nearby
- Some stat and load-out differences, most notably a LoC can take a ranged attack.
The rest is the same.
Kairos is still clearly the superiour wizard, but a LoC has some minor advantages. And there are some abilities that impact how you use the two. The LoC has a command ability, Kairos does not. Kairos benefits from being near friendly wizards, the LoC does not. The LoC has ranged attacks, Kairos is fully melee (aside from magic). Kairos unique spell summons reinforcments but the LoC has higher damage potential and doesn't degrade.
All in all this means that despite Kairos clearly being the superiour wizard, but the LoC has some abilities Kairos can't do. Imho, this is an example of a reasonably well executed named major character which is special without outright overshadowing the regular variant. There's plenty of minor named characters that are decent as well, but those are usually limited to just getting say a +1 to hit and a minor ability or unique spell, so the difference is minor enough that it doesn't really matter that they're just a better version of a basic captain-type unit.
or to make him into a nagash tecles parallel 2 units you have decried as bad disine many many times
I just meant make it a big single model, the basic idea behind that is fine. Teclis and Nagash just push it too far by having certain special rules that make them massive outliers in their respective areas. Kroak on a balewind+guards is currently 470 points, and imho that combo isn't too problematic yet. Make it roughly equal to that, round the cost to 500 and tweak some values and you probably got something reasonable. It shouldn't be as far an outlier as Teclis is with his guaranteed casts or Nagash with his 9 casts with +3 to rolls.
