Passive units

I started thinking about units that dont attack at all. Like how dancers used to be.

These units cant attack, but help other units with special abilities.

What if there were units that didnt hold a weapon, just a color. Their A skill would be used for defensive purposes only,

And their weapon skill would be special skills that couldn't be in any other slot. Such as:

Grants units within 2 spaces "Unit can counterattack regardless of distance".

At the start of turn,
Inflicts [stat]-5 on units within 3 spaces of unit

Grant's [stats]+4 to units within 2 spaces during combat
