as for bosses and resists, use rings to supplement your protection.
sometimes you will find white rings with decent base resist(above the little blue line)
you can use the Orb of Alchemy to upgrade it from white to yellow but it still keeps the inherent/base number. So your white ring with 25% lightning resist will turn in to an yellow ring with 25% lightning resist + 3 or 4 other magical benefits.
Orb of Alchemy is your best friend ...
1. change number of sockets you want (Jeweller's Orb)
2. change links to make sure they are all attached(orb of fusing)
3. change color of sockets to fit your skills (Chromatic Orb)
if those work ...
4. boom, Orb of Alchemy to convert the plain white item to rare yellow but keep all the links/sockets
life blood of building a character imo
fyi - much easier to just find the item with number of sockets than use jeweller's orb ... at least for higher number sockets.
I listed them in the order you should probably do them in ... it just works better. Sockets > Links > Color > upgrade item.
btw if you find an item with proper sockets etc you can use Orb of Scouring to remove unwanted properties. Sockets/Links are usually more valuable.
