In my case I’m half caster and half summoner, I went Cryo 2, Elementalist 1, and I use Gather Corpse a lot, so I do want INT as well, I’m pretty sure I’m changing it since I learned this game is like a game I played in the past where CON is actually the best stat regardless of class, but point being I don’t have most of my points in SPR, I got like 100 IIRC. I also haven’t bought much of the Sorcerer attribute for mana, so I do value the cat, especially since even if I don’t go OOM much on my own some bosses and possibly even players (Idk about this) have mana drains. Most BS boss in the game has mana drain that prevents regen afterwards so you need to be able to regen a lot in a small time, Idk the value of the cat buff but I’d guess it is also 50, when I first became Sorcerer I didn’t have much SPR investment and my entire life as a Sorcerer up until end of C2 I had mana issues without the cat but with the cat I was fine, so yea it’s pretty good.
If they were to change it though I’d hope they’d turn the cat into a summon that heals while also providing an aura that gives Dark Property Attack, Magic Defense and SP Regen or some kind of SP heal.
