Chief Warlord:
-banding*
-creatures you control** get +y/+y where y is this Warlord's hex bonus
-creatures banded* with this warlord get +x/+x where x is this warlord's leadership score.

*banding in MtG works like Erfworld's stacking mechanic.
**Do we know if chief warlord bonuses apply to just units of their side or all units in their alliance?

At least, thats how I picture the MtG-version of a Erf warworld working.
We have no idea how the combat stats determine combat or how bonuses affects those stats, as the authors haven't given us any real details in that area. We don't know if the bonuses add strength to the unit, multiply existing strength, or something like adding a bonus to the "dice rolls" or some wierd combination...
