Find corpses of these spectres (there is a special hotkey). Remove offering skills from trigger and spell echo from link, if any. Hover over the corpse and raise this spectre, find the next one and raise, etc. If one or all of them die, you can spam desecrate to get their corpses and raise them again.

You are also limited to one offering at a time (barring a few items to change that) so one of the offerings in your weapon will always be wasted.
