maybe add a unit that can corrupt individual enemy units to the players side, it takes time unless you build a certain amount of corruption at base. A naga would be perfect for this role.
Viewing post in Devlog, the priest & a question for you comments
honestly i love this idea but it would be cool if there was a sub system that adds eliments to all the units
you could put corruption on a unit and they would lewd the enemy unit
then you could add fire to remove clothes to lower the armor rating
acid to melt swords and weapons to lower damage
tenticles to slow enemys down
