Dwarf vs. Wingayel (Lands of Outcasts)

The problem is that he takes Wingard and boasts that HE IS INVINCIBLE!

The battle will be on Saturday (for the whole day), so I want to prepare a strategy in advance!

So, I have two choices: 1. Ingvar: go into Chaos, Sorcery, Education, Logistics (Sharp Mind), Defense 2. Ingvar (Helmar): go into Haven, Defense, Attack, Leadership, and Luck
