If you've gotten the class, you also unlocked the shop selling the equipment you need if I remember right.
Which item, I'm pretty sure the Cat has a 'damage' type weakness listed if I remember right.
Ah that’s right, I forgot that you needed a more specific item. Sorry about that.
The only Obscuring damage item at the moment is the Smoke Bomb.
I beat the cat by having :
The short answer is likely yes, you will probably need level 2 rogue and a second dexterity die.
Once you have level 2 rogue, you’ll be able to increase the damage of Smoke Bomb still further with a talent point. So that + 12 DEX + 12 CON + 1 or 2 STR + 1 WIS should be a win.
Sorry it took a while to figure out where you were at. It’s definitely an encounter I’ll be looking at further; it’s scaled up a lot because you can bring a few multipliers against it, but obviously it’s a roadblock if you haven’t unlocked those multipliers yet.
It’s a little tough to tell where you are in the Rogue arc, but if you’ve gotten the Rogue shop and aren’t level 2 yet, you probably need explore the Upper River District. Once you’ve complete the jobs there, you’ll have a few more chats at the Selky Pint which will give you another job and level 2 Rogue (obviously this is a top-level overview).
The Dunhaven Heist involves a set of evasion and mechanism encounters that are generally quite a bit easier than the Anemic Cat, but you have to do them all back-to-back. Checking out the estate beforehand can make it easier, and you might learn things on a run that make it worth rerolling/restarting the expedition.
If/When you complete the Heist, you’ll return to the Selky Pint to report your success, which should carry you further along the Rogue Arc.
