Divinity: Original Sin 2: Larian doesn't know what 'original' means

[Keltest]

I've actually been concentrating on Con and my main damage stats, with occasional points into Memory. I've barely been touching Wits--I think the 2 points I put into Ifan's Wit when I went from level 17 to 18 were the first ones I'd put in there.

Survivability is pretty darned good, though, he's got over 4000 hit points at this level!

Wits are important. There are quite a few quests you cant finish without sufficient wits to locate hidden objects like switches and levers that let you physically advance.
