Any guesses for Boromir, as it seems rather probable that he was mentioned for the Dead Marshes expansion... You can put what you'd like to see and/or what you expect seeing.
I'd like something like this:
Boromir
Leadership Sphere
Gondor, Noble, Warrior
Threat Cost 11
Will Power 1
Attack 3
Defense 2
Hit Points 5
Boromir can be assigned as a defender to any number of engaged enemies.
If you attach Horn of Gondor to Boromir, he gains a Tactics resource icon.
I realize it seems quite too strong but I'd like that. It would give Horn of Gondor a much better use, as it is sort of weak right now. I'll be happy if Boromir is Leadership and not Tactics, it makes more sense to me when you already have Theodred and Faramir in the sphere, as opposed to having Legolas and Gimli in the Tactics.
PS I expect something different although all the (5) numbers are hard to imagine differently. And the defending thing is quite thematic, I believe.
