I think aside from my +1 sword I had a few potions, a ring of blending (I don't remember the details but it was like a camouflage spell or something), and.... uh... some kind of other magical ring. The mage made tons of magical rings of something-or-other because we led and expedition into HELL (yes, at 9th level) and the mage hired a small army of heroes and mercenaries to get us through, equipping us all with these rings to do so.

Back in those days a good DM and lots of imagination went far. You didn't have to make an entire build with a feat tree just so you could hire some mercenaries or build a siege weapon. This is why I like AD&D more than 3.5 despite the ridiculously designed stats system. in AD&D it really felt like nothing was off-limits.
