Put some training points into archery (or level it up a bit), fill up like 5 bags of arrows, get someone in Everfrost to sow you and bow kite
Karg Icebear for a Gigantic Zweihander (18/39 2H). I did it at level 20 on green with 2 bags of arrows and no sow (20 minutes of strafe running and jump shotting sucked). Can do the same in steamfont for the minotaur for hero bracer, though as an ogre/troll, im pretty sure you can't wear it.
Might be some other quests that involve killing that a self-found character can bow kite much earlier than you would typically be able to kill something for a nice power boost.
Also, PGT from Highpass is really good at low levels. In the teens, the proc will absorb a hit from a lot of mobs and helps mitigation a lot for soloing. Could probably get a duo or trio to kill it around level 15, or solo closer to 20.
