I have done so much forum searching but found no answers and I think I'm just being really stupid and missing something obvious, hahahah. So I'm asking here. I have two main issues.

One is that even if I pick an element that recommends itself for agility I then cannot add proficiency points to agility, it's greyed out. Do I have to hit a certain level up be able to add to that and if so what should I put my points into until then If I want a mission pet heavy on agility?

If that's not the case then why is it greyed out and how do I fix it?

My second problem is that everywhere tells you to put your proficiency points into your build, and also your level up points. Well, I can't find those anywhere. My main battling pet (for now, going to put more work into proper set when I'm higher level) is about level 17 but I am completely unable to find her level up points to use them. It's this an outdated system I've found guides for, or am I missing them somewhere really obvious?

I hope all that makes sense. I'm so frustrated with myself because I've spent AGES trying to work this out and I bet it's really simple :-D

Thanks so much for any help given! You guys are all sweethearts. FYI despite my fighting/mission pets refusing to behave I'm REALLY enjoying the game. It reminds me a lot of a long-gone pet game I used to love and played for years before it sadly was closed down, so I'm very very happy to be here <3 Please don't take my frustration with myself as dislike for the game, I'm really enjoying it!

Anything which talks of proficiency points and level up points separately is at least somewhat outdated, as there was a major overhaul earlier this year which combined them into the new system.

I can't remember exactly what it is, but I think it's until you get your first pet/your level over level 30 (not your starter, just a pet, because the highest level you've raised a pet to is what your user level reflects) that you have to pick either HP or Int/Str to put your first point into?
Alternately, it's to do with the tutorial completion.

There's a comprehensive guide here in the player guides forum.

Thank you, I'll have a read of that today. Very appreciated :-)
