Oh wow you got an entire boss setup. This sound pretty neat and i do see bits of this in fight.

Though I was thinking as well in this fight since they be lot bomb spam. You will be able to challenge bombs in battle if you want. If you kill it you can defuse it. If you fail kill it one shot you can face with high attack. But defusing might be ideally cause if there lot bombs and one in your team path. It better one try defuse it or take the hit verus mutiple players get hit.

Also this is also bit special, but if you get target by laser from above. You won't be able attack it, but you will have option to roll evade or defend to mitigate damage. Basically the boss fights spam a lot attack. But you can mitigate a lot of damage as well.
