Shadow knight Epic (Innoruuk's Curse), Faction question

[Jimjam]

Faction question regarding Shadowknight Epic Innoruuk's curse.

I noticed the epic quest seems to involve a faction mechanic using Truespirit, possibly similar to the shaman epic.

Like the shaman epic, is it possible to skip some steps by grinding faction or even using invis/feign death?

As far as I can tell all the first step (in Overthere) seems to achieve is an increase in faction and a plat/item sink?
