Boots:
Sandstorm trecks = 70 pr
Rare = 40pr, 25plr possible up to 75plr?
Amulets, diadems up to 75plr, and poison res.
Andariel face GUL = 15max poison res
Snakecord = 50 psn lenght reduce
Death gloves = 50pr and 75plr.
Antidotes...
Antidotes are bm for pvp. But you can make forexample es sorc immune to poison in good ways, but it require good gear.
You can think of poison res as normal res, max psn res as increasing it further and PLR as absorb.
Lets say a java cast a 70k damage plague jav on you.
But your a sorc with:
Death Gloves
Snakecord
75plr in amulet
50plr in boots
And 75poison res in hell, and 75 plr in hell.
His damage:
70000 * 0,17 * (1-(75/100)) * (1-(75/100)) = 743 damage.
I just wanted to say that I appreciate the breakdown. thanks for your time.
