well... for starters, runes are your friend. well... not really, rune WORDS are your friend. stealth armor (tal eth), lore helm (ort sol), and rhyme shield (shael eth) are the strongest runewords for low levels. those are basically your res/good stat items. one other rune word you might want is leaf (tir ral) for a weapon, its normally for a fire sorc, but it gives + mana after kill and warmth, which is always good for low levels. for low level mfing, your going to want ptopaz's, find some 3/4 socket armor and 3 socket helm and put ptopaz's in them. thats about 150~ mf right there. pick up ALL your rares. some rares are actually good, especially boots, i've found lots of rare boots with 10-20 mf and some res, same with gloves. and hoard ALL uniques and sets you find. you never know what people will trade for. i got a lidless for a normal topaz, so you never now when you might find a real steal deal. magic items are the same as rares, they could have mf on them, and every bit counts normally. try and get some high level friends. they will sometimes give you free crap thats actually good. there are lots of exceptional uniques that lots of high players think are crap, but for low level players, their god sends.
just play conservitavly and run what ever bosses you can, you ALWAYS eventually find something of trade value.
also,
your a light sorc? you should be fine in the damage department. lightning does good damage, so you wont need to sacrifice many +skills items for mf items
