A Mountain Tamer's Best Friend

I had a fairly high level Megalania, and at the time I knew nothing about the breeding process. At the time, I think she was Level 210. My friend was traveling with me, and I used my Megalania on a near-vertical surface on the volcano on The Island. He was riding a Baryonyx I lent him. We were attacked by a high-level Rex, and I made her grip the volcano's surface just above the Rex's biting range. My friend kept tabs on the surrounding area, while I kept baiting the Rex into my crossbow shots. Too bad I lost that Rex, but I was a rookie back then :P
