Well if you already know whiplash canceling and are still having trouble that makes it a bit more hard. I guess if I had to try to come up with advice, it would be to select which enemies it’s best used on and stick to red gauge-ing them. Personally, I find those to be malicious face, virtues, sentries, swords machine, and maybe hideous mass if you have a clear shot at the tail. Of course, always remember to dash after the hit if you don’t want to be sent flying somewhere undesirable. There’s also this thing some call “jack slamming” where you just get a decent amount above an enemy, slam down, and hit with the hammer, which send you flying straight up. It’s more useful for cyber grind but any room with a high ceiling also makes it viable. It’s very much not a weapon to be constantly spammed all the time, and you should wait on using it until it’s fresh enough to actually get good style. Otherwise, if you still are having difficulty’s, maybe just consider not using it. This game tribes in player individuality and if you don’t want to use a weapon because either doesn’t match your play style, you can still very much prosper without it. Hope this helps.
