In this video, I show what boss battles will be like in Tunnels of Doom. Unlike regular enemies, bosses are 4 times the size and I use pictures instead of events.
Bosses choose random spots on the map when they move, and will trample players if they happen to be in his path. They may use their special attack to throw something at the player.
In this video, I don't attack the spider on each turn, since I'm fighting it with a team of 4 with good equipment. In the actual game this boss will be fought by Alex and Jason with starting equipment.
