With the new skill Necromancy coming out, I think there should be an update to Implings.
Create a new impling that goes with the skill. Since we know nothing about the skill yet, I won't offer any name suggestions.
While at it, perhaps an Ingenious Impling in honour of the Invention skill, and a Historical Impling in honour of the Archaeology skill, can be included. They would of course carry various loot associated with those skills.
Perhaps. We'd need to know what the Necromancy skill is all about first. I'd say leave the Zombies for their bones, and create a new Impling for Necro. Also, no point in overloading Zombies with more items, especially if bones have no use in the new skill.
