Ooops
thx for correcting me.
Leadership limits
Of course reinforcements should be capped by leadership limit.
Costs
* Iron Fist - pay gold to summon reinforcements from your reserve slots (1 stack per turn). Gold = Stack_Leadership x 10. IronFist level gives you discount equal to it's leadership bonus for human troops
* Necromancy - pay mana
and gold to summon reinforcements. Gold = Stack_Leadership x 10. Mana = constant value based on Necromancy level.
If u don't have nough money, then their quantity should be limited to Leadership x 10
what d'u think about it?
