As for the other proprietary spells:
- Battlefield relief is fine as is. It shores up a weakness, costs a lot, can only be in one place at once, comes at the same rex as the spell it autocasts. Seems ok to me.
- the battlefield wide elemental resist is OK, that's something forced no-diversity Ulm can certainly do with in the long run, but it should be rex level 9 just like Gaia's Blessing. 6 is just insulting, even more so that it's in Construction and comes in the guise of a really powerful mage with a high forge bonus to boot.
- auto solar brilliance is probably OK as is.
- auto luck must go. There's a reason the Sword of Aurgelmer is an artifact - turn 0 will of the fates is
that good. Luck is non-thematic for Ulm anyway, they stand against superstitions like these. Then again, it doesn't seem to be working ATM, so that's moot
(or is the Relic of Steel supposed to be doing something else ? I'm not seeing any effect). You already have access to Will of the Fates normally using matrices on S Smiths or Icons of the Forge anyway.
- auto growing fury is also immensely powerful with the kind of troops Ulm can use it on. It's like getting army of leaded Maenads, but much earlier and also better because you're getting even higher protection out of it and your "Maenads" can actually kill stuff but good. It also doesn't make much thematic sense, if Ulm is supposed to be the logic and reason no-nonsense empire, to rely on frothing madmen. Make it cast fanaticism instead if you really feel like BR Ulm needs to also be preternaturally good vs. morale effects for some reason, and lower it a bit in both research and gemcost. 4 and 10 maybe ?
- the Cursed Icon is really powerful. But then again it does cost a mint and come in late...but then again it's sickeningly powerful and that's without even gearing him. Compare him to an Ember Lord who's much harder to cast, costs one and a half times as much, and doesn't come inbuilt with nearly as much of the good stuff. Or to Cyclops/Asynja, both of whom cost about the same and have almost
none of the good stuff. Granted, they will
eventually disease themselves and
eventually will get some of the bad afflictions from that disease (most of the afflictions won't actually hinder them one bit), but still. To top it all they're in Construction instead of at or near the end of a completely different path, like all the other SC chassises, further cementing BR Ulm as the "I only need to research 2 paths to win" nation.
As an aside, why did you feel the need to give all these guys Blood Vengeance/Fear/Awe anyway ? Autocasting the best spells in the game without having to bother with that diversity malarkey wasn't enough, they also had to be able to be awesome high end thugs for good measure
?
