As to how the boss handles combat, a number of different techniques can help make boss fights memorable. You can use fantastic terrain like magical crystals that shield the boss, or a chamber that slowly fills up with poison gas to hinder the heroes. Or you can protect the boss with powerful guardians that absorb damage or powerful effects. And it’s worth remembering that no boss should ever fight alone. The challenge in any battle comes from the number of monsters the characters face—but in boss battles, this becomes even more important.
