Lotl-Botl does not like giving ground in hand-to-hand combat. If the enemy are coming at him from all sides and trying to overwhelm him, it just makes him angrier. He wades into the pressing throng cutting a swath right into the heart of the enemy unit, yelling to his warriors to follow him. They are inspired by his presence, becoming harder to beat in close combat.
Any unit of Saurus Warriors Lotl-Botl joins gains a +1 bonus to their combat resolution as long as he is in the unit.
