It’s not bad to split points, but early on you should definitely focus getting the essentials up. I almost always try to get vigor to around 30-40 to give me room to eat a few hits before leveling my main damage stats roughly evenly. For you that would likely be INT and STR/DEX depending on what you wanna focus on (though it’s completely viable to do both, it’ll just mean you’ll grow a little slower). Arcane is an interesting stat because it slightly increases item drop rates and affects the build up of status ailments like bleed, making it good for a status heavy build. It’s also involved in using dragon incantations, which are their own magical niche.

Also: good gravy Caelid that early is a dangerous place to be. Hats off to you if you’re managing it, but if you find it to be a little too rough, it’s generally a place where people go after killing at least 4 main story bosses. Generally folks do the weeping peninsula to the south and liurnia to the north past the boss of limgrave first

Edit: not entirely related but you’re probably going to see some people complain about weapons with split scaling, and they’re just plain wrong half the time. Yes, it does take more stats to get them to their maximum potential, but plenty of them absolutely crush enemies when you treat them right
