Ok so i needed to farm for Essence of Singularity which imbues DCI.
so i got in my imbuer and turned on Neos weapon crafter, got my self a three double axes, one spell channeling, one poison ele slayer and one elemental slayer for the renowned, I imbued all to have hit mana and stamina leech, the elemental and poison slayer both had some SSI on.
i headed down to the Abyss and the spell channeling double axe tore through the sllimes with no worries, poison eles spawned and i swithced to my my poison ele slayed but the acid eates through the durability far to quick to use it for more than one spawn before repairing so i swithched back to my spell channeling and not much damage reduction, sp poison eles no problem.
Then the Interred Grizzles spawed and i got killed after attacking a few, i quickly realised it was to do with the fire acid they drop on the floor that you have to move out of, once i sorted that they were no problem.
Then the Renowned spawed so i switched to my elemental slayer, same thing with durability, it wore it down way to quick so i swithed back to my SC double axe and not much damage loss.
so in hind sight i only needed to worry about imbuing one spell channeling double axe to save durability on all levels of spawn, although ive done 3 spawns and my durability has dropped from 255 to 80 so ill need to repair soon.
hope this will be of some help to some one.
cheers
