When unlocking magic how much stat is it worth to convert into mana ? I notice there's several -10% -20% mana cost items, so eventually could i reach 100% mana cost reduction?
I can get at least 40% so far -- and the wine item gives efficiency too, though not sure what %.
You can also get extra mana from skills, so you don't always HAVE to sacrifice hp/stam. I personally went in for +2 (-10 to each, +40 mana) and figured I'd make up the rest elsewhere. Since mana doesn't regen on rest, which IMO is a neat mechanic, you kind of have to rely on mana restore items anyway. Blue shrimp are great for that.
Side note -- the game has a lot of novel or uncommon mechanics which I like, and most things about magic are in the direction that I want magic to function instead of just grenades-by-another-name. Hopefully the spell selection keeps up.
Regarding combat -- most normal monster/beast enemies aren't worth fighting unless you specifically want the crafting materials. Humanoid enemies however drop their weapon (which you can tell what it is, if you want to loot it) and can drop money, potions, armor pieces, etc. At that point you have to do a risk-benefit consideration. IMO the fact that combat isn't always rewarding is a good choice, and the lack of an XP gauge further reinforces that your job isn't to be a genocide machine.
In any PB game, I would systematically murder everything in my sight for precious precious xp and loot, but in this game I often just avoid it. Elex helped remediate the need to murder everything as well with 1) difficulty spike early on and 2) absolutely shit xp (not to mention respawn).
It's not shocker that a person's enjoyment of a game depends on how many of the systems/elements they like or dislike, and in my case, almost all the elements are ones that I do like... but wish were more fleshed out.
If they do make a solid add-in DLC, it could easily give this game a huge boost. It has a decent base for simulationist time-wasting/grinding that's enjoyable -- if they really just flesh it out with more stuff to do, more ways to do it, and more emergent situations, I think it'll benefit massively in a "whole > sum of parts" way.
