If I Zeta Cassian, under mothma lead, would they get 20% protection up before or after her leader bonus is calculated?

Kyno

it doesnt' matter, the way they calculate it is
[base stat + (base stat x 20%) + (base stat x leader bonus)]

One does not feed the other. each one is calculated from the base and added to the base stat.

Most uniques trigger before leads and typically don't compound
Few rare instances where uniques will compound with each other.
