True, but incinerate doesnt have any real bonus effects and the explosion damage is too tiny. I would have had better luck spending the points on the Attribute+.
It is because Kodo War Drum was built as a unit skill, and Yoshi didnt takje into consideration implementing it as a Hero skill very well. It is like what happened to the Footman. I think of the upgrades is missing on him.
But because of him, a firelord, and a kotg. We did manage to slay the boss inside that maze temple including Shandris with ease. I also have a replay of this game.
