Allows players to promote another unit so it can recruit, the unit promoted this way is expendable as long there is more than one unit that can recruit.
To promote an unit it must be level 2 or greater, have full moves, be standing on a castle or keep hex and standing adjacent to another unit that can recruit of that side.
Upon promotion the unit cannot move or fight for that turn.
Update 1.1: Made this modification playable with my other mods: 'Spoils of War','Heroic Leaders' and 'Assimilation Mod'. Killing an silver crown wont cause that side to lose all units or their gold anymore. Also silver crowns wont potentially get heroic trait at begin of next match during an mp campaign(citation needed).
