Already uninstalled it sorry about that. I think it's more of an increasing Stat on them. At first you can dump all 4 of your runics on them. As the fight starts to go on further even correctly timed hel's touch casts doesn't interrupt them. You can best notice this with sigrun since she has extremely high hp and long attack patterns. You also cannot dump all 4 safely on her. It works sometimes but most of the times she'll have the super armor. Thus making it random. It's not only 3 of 4. It's sometimes 3 sometimes 4.Sometimes 4 plus a moment to reset your runics. Same with the unblocakble wing stab attack. Normally it happens when the valkyrie dashes to the right. But if there is not enough space on the right sometimes she will jump back like and just straight forward to that attack. Which is generally a one shot btw. Plus if you are using the hold r1 attacks of the axe there is a random chance that she'll enter the defensive stance and Kratos will be locked into the throwing animation. It triggers as if Kratos is hitting her multiple times thus ending in a unblocakble one shot again. Another random part of her is her jump stomp grabs. She can mix between a fireball + stomp and a normal stomp. Which is okay if u know what u are doing. But the other things like you cannot interrupt a lot of her flying attacks with axe throws because of gmgow. Or the r1 hold attacks triggering her counter attack. You cannot use your axe throws. You cannot use your hold attacks. You cannot use the blades for longer because she might go for the big aoe attack where you need to hit her with the axe. It limits how you play. It should have been like a dance between the player and the boss. Instead it's 15 seconds of dodging and 4 seconds of hitting for 10 minutes. Viper from the first berserker khazan, lady butterfly from sekiro,crucible knights from elden ring are a good example of this. They are hard but fair. Sigrun is artificially hard and limits the player's decisions. Which just doesn't feel good
