I see what you mean about PE: Orks. Duelist seems fair enough, and applicable to everyone. i would much rather take a melee speciality for the chapter vs a shooting one, since i feel it fits the chapter better.
Stalwart is my preferred between it and warded. i really like the fluff bit for it:
How does one defeat warriors whose willpower and determination are so ferocious that they can shrug off even the most catastrophic injuries and keep on fighting?
it kind of reminds me of the Grim Resolve wording:
The stalwart descendants of the Lion are renowned for their unshakeable resolve, enduring tenacity, and strict fire discipline.
Although not exactly the same, it speaks to the character of all Unforgiven. The Iron Lions are steady in their advance, their augmented bodies as enduring as their resolve.
I like the idea of "Iron Will, Leonine Determination". With some tweaks, i would like it to represent the chapter tactic as a whole, instead of just the stalwart half of it. similar to how the other chapters have Grim Resolve, Siege Masters, No Matter the Odds, etc represent the whole chapter tactic. Names could be:
Iron Will, Leonine Determination
Iron Resolve, Leonine Ferocity
Blessing of Iron, Fury of the Lion
The chapter motto, Honour the Legion
thanks alot for the help Bjorn and suggestions.
