Can't you come up at least with some epic deeds?
I have now given his background for everything but his leadership, and I have done nothing for Fak as yet. Working on doing a lot of stuff right now, sorry about the delay.
I am pretty sure the level of
stupidity 'desperate self-sacrifice and bravery' (since it worked) that was employed to hold the line would be enough to fulfill the prerequisites.
For leadership: is it just the cohort, or are there followers too?
Can he have his followers be "slightly mutated Baby Dodongo's" (Muckdwellers with levels in Swordsage, Blistering Flourish being their 'explosion' that doesn't kill them because of their 'mutation')?
If allowed, I'd basically have all of them be carbon-copies of each other (because, in part, it is as if racial, not trained, abilities). The stance known would be Stonefoot Stance; The maneuvers readied would be Blistering Flourish, Distracting Ember, Sudden Leap, and Wind Stride. Their only feat would be Adaptive Style (to refresh all of their maneuvers with one full-round, instead of one maneuver per full-round). Right now, there would be eight of them.
I would endeavor to keep them away from bombs. 'Weakness' not-withstanding, 4 HP doesn't go far.
If allowed: I plan to have Veres to have rescued their swamp-grove from an attack... accidentally.
