Can Convergent Mutation be used on a unit with higher might than the target 'another friendly unit', and would it lower the might in that case?

Ruling: Convergent Mutation can only increase a unit's might until it equals another unit's might. It cannot lower might.

Nuances:

• The ability only works when the target unit has lower might than the reference unit
• If the target already has equal or higher might, the ability cannot be used to reduce it
