As trying to do a no upgrades run with Fabianne. I had some caveats with her.
1 there is no indications where is the nex attack a grinding attack or a normal one. Sometimes very fast attacks it grinds you while slow ones don't do nothing. It feels luck based when it happens or not. Like sometimes you get 2 times in a row and other it doesn't happen.
2 sometimes she would home you an attack without her waiting. It seems that it happens because it spawns outside of your screen so you don't have time to react that is coming after you.
3 a lot of people could probably miss the sound and shakes queues on her fight. So maybe a remider on the fail state could be helpful.
Still trying to beat her without upgrades i got firendship 3 but i got smushed at the end.
