“Trials of the Undying” is designed to put a party to the ultimate test of endurance and tactical ability. There are minimal opportunities for roleplaying or typical exploration challenges. Instead the adventure is focused on combats and high-tension moments with puzzle elements to confound typical D&D 5e strategies; simply rolling initiative and attacking blindly will not suffice here. The enemies and hazards will require groups to utilize all of their abilities to the utmost while also identifying the strategies necessary to disable the most deadly elements of the encounters. It is recommended that players be very familiar with the rules of combat and that they also be prepared for the worst to happen. Without good strategy, death is very likely to occur.
