Flaming Rock and Mud are both Terra based dragons. The critical attacks on Terra are Metal and War. Without a Metal or a Metal Hybrid you are going to have to duke it out blow for blow. Shogun will work since it is a Metal primary from the Japense Island quest. Thor would work against Flaming Rock but would not work against Mud.
