Did you typo "curse?" If there is a curse bug, I don't know anything about it. The only frequently talked about necro bug I know about is the marrowwalk bug which gives you 33 synergies to bone skills if you wear marrows but don't have any points in bone prison.
Wear Marrowwalk boots. Don't put any points into bone prison. That's it.
It makes the game think you put 33 points into bone prison. This will give you huge synergy bonuses to teeth, bonespear, bone spirit, bone wall, and bone armor without spending a point on bone prison.
This works with other items like the Carrion Wind ring for druids. It has a level 21 poison vine charge on it which gives the wolf poison attack free synergies. But once again you can't put any points into poison vine or you lose the bonus.
Ok in US West ladder a pair of marrows will cost you 12pgems-lem. I got mine this ladder season for 5 rals ^^ from a crafting addict hehe Look for ones with +2 skelly mastery and this ought to take precedence over +str or ed if you want to go bone/summon hybrid especially IMO. Trap/22 life gc is worth um-pul or mal i would think and could get you a plain PnB GC I have a rough guide on dmg output from a poorman's and richman's bone/summon mf necro employing marrows if you are interested:
p.s Carrion ring is used to synergise rabies while molten boulder charges from 'Stone' armor is used to synergise fireclaws...and give other chars the pet clay golem experience hehe Oh and 'Beast' + Wolfhowl to give meaty grizzly
If you don't know "what are synergy", then perhaps you should do some background reading on the game before rushing away to trade.
Also, do you mind fixing up your spelling a bit? I like people's comments to be challenging because of the ideas they express, not because of their horrible writing.
