I'm currently considering working on a couple loadouts for when the event arises. Basically, I'll be going grindhard in Kat maps in search of Ancient Pages and a Book of Dark Rituals.
Anyway, I'll be listing multiple loadouts here. One set will be for Kat-Fighting, one will be specifically for fighting Margrel. For short, I'll be calling the event Katfrontation when necessary.
It should be important to say that the Kat-Fighting Set is typically going to be used for solo'ing, while the Margrel set is for playing with others.
Please note that normal, poison, and freeze kats are the most common. Curse will be on most armors I list, though.

If you have any idea for gear I don't have listed, please do note them if you think they will be effective against kats.
Choose what loadout you think would be best out of the weapons I listed!

*I don't care if I catch fire from the Fang of Vog. Remedy Capsules? What are those? There clearly isn't a pickup vendor on Moorcroft.
**Margrel has a relatively wide hitbox (as you would expect), so it would fly into every shard on the ground.
Blitz is probably great single target damage to kill the Kat before it gets too spawn-happy. I'm personally leaning toward iron slug to snipe the Kat inside it's cursed skelly cover.
I like AP for breaking blocks, and hammer as a multi tool for killing and speeding through the levels.
