Boss Weaknesses?

[Josh Mystic]

Forgive me if it seems like a stupid question but I don't know how to figure out which boss's power is the weakness for another boss, is there some way to tell or figure it out?

Usually it's trial and error. Or checking the guide.

If you nail the boss with a weakness, the text will appear yellow with a !!, the correct Power also has special effects beyond its normal utility effects on the right boss or its attacks, from making them break off their attack, to reflecting or exploding their attacks, to even freezing them solid

Also, every Power has a special effect outside of battle, experiment or dig through the guides to find out more
