What level were you when you started working on a new skill tree? Right now I'm a level 23 Spellsword and I just started working on conjuration and enchanting.

level 54 with the one-handed tree. I started when I realized that I had level 85 in it, with no perks at all.

I'm currently level 27 and just starting a couple of new skill trees. I got my character up to a point where I was happy with a few of her skills and am now developing her a little more

Me too actually. Level 27 and only invested perks in 4 trees. After 30, I'll probably branch out into a couple more.

Level 44 before I actually started putting points into Alchemy.

Level 33 on my main Dovahkiin character, and I just started to learn Archery - which is currently at 33 and one perk.

Gonna be a LOOOONNNNGG time before it can help me fight dragons. Heh, I've still got my good 'ol Thu'um for that.

Yeah same here, my warrior retired and studied Enchanting with his last 6 perks.
