I know it is a common feeling among the community that corruption seraph is the hardest, but after playing through close to half of the cov 10 combinations with titan kills as well, I have to say rage seraph is almost certainly the hardest at this difficulty level, and definitely feels like it needs some tuning done to make it not be such an outlier.

The first thing that makes it harder on cov10 titan runs is that the titan trial makes the rage seraph fight disproportionately harder compared to the others. By slapping 2 melee weakness instead of 1, that means a tank eating seraph's attack needs to survive at minimum 90 incoming damage, a pretty high bar to reach. By applying rage 6 instead of 3 to a floor, it all but ensures that if the sweepers attack, they will be killing your backline, especially when you consider the elite versions are there with multistrike too.

Compare this to the corruption fight. Yes, seraph now applies 4 corruption instead of 2, but he still doubles corruption on his attack target as he does normally. The extra corruption on your backline DOES make it harder to keep them alive, but not to an insane degree. If you look at the sap fight, the titan challenge does almost nothing. Sure your units get more sap, but odds are if you're able to beat sap seraph to begin with, you have scaling damage, which means the increased sap just makes it take 1, maybe 2 more turns to get past it.

The second thing that makes it harder, and in my opinion what should be looked at for tuning, is the waves. They require a lot of answers, and each of those answers need to be GOOD answers. You need a way to deal 50 damage every turn to backline enemies, and you need to be able to do it before they attack, because the sweepers attacking is devastating for all but the most extremely tanky decks. Inferno room is of course an easy answer technically available to all clan combos if you can find it (and make it deployable), but besides that, answers are very hard to come by. And, even if you DO get the inferno room, you're still punished for that by...

Amalgams, these stupid birds paired with the sweepers are almost guaranteed to strip anywhere from 20-60hp from your pyre depending on your setup, and that's assuming you DO kill them, they'll do much more if they leak, which isn't uncommon given they have nearly as much hp as...

Heavies... 500 hp, ok, I get it, I'm supposed to have a lot of damage. Why in gods name am I expected to bash through multiple 500hp enemies in one turn. The answer may seem like killing them on all floors, but this isn't really viable in probably 90%+ of decks.

The combination of these guys, while they're getting 12 damage from seraph every time he shows up on the floor with them, AND you have to eat a +200% damage hit from something with your tank, feels utterly ridiculous to deal with. None of the problems it presents are impossible to solve, and none of them have only a single solution, but it asks you for SO MANY solutions that the other fights simply do not. They have aspects that can make them harder to beat for certain decks, but it always feels so much easier to prepare for a corruption or sap seraph than it is to prepare for rage seraph (I often find myself just praying to find a deployable inferno room, or at least a non-deployable one if nothing else).

Anyway, I'd like it to be toned down just a bit. I don't think it needs some huge nerf, but taking off some hp from amalgams or the elite assassin, the trial adding 1 melee weakness+6 rage instead of 2 melee weakness+6 rage, or 1 less unit on a wave or 2 are thoughts I had, but of course any change would be appreciated.
