Greetings Pathfindarians, I seek your advice. The spell Mage Armor isn't on my list, what's the best way to acquire this spell without having to spend a feat.
Without spending any feats will be hard but Trick Magic Item skill feat can help you with scrolls/wands of mage armor.
Get light armor via general feat or something like rogue dedication instead. By the time the not scaling becomes an issue, you'll only be a few levels away from 20 Dex which is enough for max AC without armor anyway.
All this assuming you start with 16 Dex of course.
