I'd prefer for the King to attack and retreat, and they know it is constant threat in the city. Also, i would personally have it resurrected at a later date, or another dino is upgraded to the King, so that there would always be one in Omu.
In part two of the encounter he did that. Teleported in, bit and grappled someone, and then teleported out - with the victim still in his jaws. None of the characters in my game are bags of hit-points, so the character in the jaws only had 1 hp left. The only reason he survived is because I kept the teleport as being line-of-sight.
Good idea on Drungulungalungulung. I'd be tempted to do the same, but have worked out a back story for the return of one of the characters whose player has been away for 6 months. He was captured and taken there. The player should be returning later this month.
