Nemesis System
Maybe ridiculous, but hear me out. What if we had Shadow of Mordor's nemesis system implemented here- like maybe the evil god in Noble Fates links the slain orcs/any other race planned to himself and gives them life. A limb system may also be put in place so your nobles can hack legs, heads, etc so that when nobles cut any part of enemies, the evil god linked-being revives without the hacked body part. This being will revive again indefinitely when killed and grows stronger each time.
-For your kingdom to counter this, your king has the ability to remove said evil link to prevent resurrection, or convert him to your cause.(not guaranteed.. rng will be at play).
- Evil god-linked nobles will infiltrate random kingdoms and will try to steal the throne from their kings.
- Evil god-linked nobles that were converted to your cause can also indefinitely revive and serve you once again.
Ya this is cool - would like to do more with returning nobles and long lasting injuries and such.
