Man I'm 15 1/2 on alv and I don't feel done. The only PVE thing I took was butcher (gonna unspec tho at some pt when I can stomach the loss of exp, yea I kno the longer the more I lose.
These are the skills I have: long life, resting pulse, both runs, archery, both bows, both run shouts, psyche/butchery (ones I prol don't need,) dark vision working toward weak spot, +4 dex, stalker, and combat leap of course. So even if I swap butchery out, I still gotta get aerial, then maybe think about getting some pve stuff or vital/other pluses. Plantshaper is gonna be nice cuz I'm a cook, and I kinda hope it goes into adv dendro, but I bet it doesn't.
I think Alv is one of the few clades that could legit use 20. The rest could get close to 20 with just attribute buffs and passives.
