Gustor - Son of Skrung - Level 20 Elite Soldier

Two things to bear in mind (with all my monsters)
1) The defences assume you use the Escalation Die rules from 13th Age. If you don't, I would drop them by 3
2) You need to add half the monster's level to the ability mods to get the total score. So, Gustor's Strength mod is +23.
