Can't defeat Bagud!

[Openingknight]

Thanks for your help. My stats are:

Attack 10
Defense 25
Rage 67 (0 at start of battle)
Mana 91
Intellect 10

Leadership is 22,400

I have most order spells at level 3, and most distortion at level 1

My "Time back" works on level 1-3 creatures

The only troop affecting artifact I have is "knight boots" which give +5 defense to horsemen, swordsmen, knights etc. Other artifacts affect any units with attck/defense bonuses.
