I read about an approach for posting possible spoilers, so I’m trying it out here. Apologies if it takes a few edits to get right. But:
Tips on the Anemic Cat (click to expand)
- It's an evasion encounter.
So roll a Rogue with High Constitution & Dexterity and equip yourself with an item from the thieves' guild. - Like the other animal encounters, the cat scales its damage based on some of your stats.
So your Rogue should have as low Strength & Wisdom as possible (literal 1's or maybe a 2 in Str if you have to). - Late Edit for posterity: The cat is a Focused evasion encounter.
So it takes more damage from Obscuring abilities (i.e. the Smoke Bomb).
Hope this helps.
