I'm making a list of builds that can do players 8 singleplayer with garbage gear.
Junk gear means gear you might reliably be able to find without excessive farming or any LK runs. Not as hardcore as single pass playthrough but close.
This is what I have so far.
Summon necromancer, I usually do maxed revive because skeletons get wrecked players 8 wih junk gear. Lots of mana pots for revive spam.
Trapsin with fireblast maxed for immunes, mindblast is OP
Bowazon with knockback on gear and lots of time and arrows, possibly do strafe/freezing arrow hybrid
Fireclaw bear with a handful of points into shockwave
Sorc with blizzard, meteorb, etc with half decent FCR to kite forever
Javazon with maxed valk or decoy and semi decent javelins for jab
Hammerdin with lots of kiting, vigor helps
Bone necromancer with liberal use of bone prison and lots of mana pots
Melee barb that taunts enemies one at a time offscreen, extremely slow, most any skill would work.
Warcry barb with essentially infinite mana pots, might have to actually use find potion skill to avoid being permanently broke
Anyone else have any other ideas?
