Ttharg Krixkrux
Ttharg turns away from the explosion and shields himself as best as possible against the raging inferno.
As it subsides, he quickly pats down any parts of his clothing that caught fire and assesses the damage to the crew with a practised eye. He sees Fork on the ground, charred, but not burnt to a crisp. He is too far for Ttharg to use his medical kit or hands of healing, so instead Ttharg speaks words of healing power to him. "O' the call o' the sea is mighty strong, it calls to ye and it calls to me!"
Ttharg then begins to wade into the swamp water proper, to close with the new Slaad. He is forced to leave his Spiritual Weapon behind for a moment, but swings at the new Slaad with his Warhammer.
