Hey guys could you give me a price check and the following item

Halves casting time of death magic spell (chance 19%)

Also could anyone tell me how much a rune of superior absorption is actually worth??

Last time I checked the Absorption rune wa at 550g at Trader, as for the Staff, its Merchant food/Salvage IMO, lackin the second mod.
