Doctor Piersym, Bove, and The Storm Lady | New BBEG for Fifth Edition

Doctor Piersym

Doctor Piersym is a lawful evil male human noble with the Mad Scientist Boost (see below). He is the creator of the Tempusfuge and hopes to study its power. He also creates the flesh golems that protect the Storm Lady’s Maze. While loyal to the Storm Lady, he would quickly switch sides if he felt endangered by his relationship with her.

Mad Scientist

Prerequisite: humanoid

The creature is a mad scientist, capable of creating fascinating (and often gruesome) inventions. It gains the following benefits:

  • The mad scientist has advantage on its Intelligence saving throws and ability checks.
  • The mad scientist is armed with a lightning gun which it can use to make ranged attacks. The lightning gun’s range is 30/90 feet. On a hit, the gun deals 1d6 lightning damage.
  • On its turn, the mad scientist can use its bonus action to empower one construct within 30 feet of it that the mad scientist can see that can understand the mad scientist. Until the end of its next turn, the empowered construct can reroll any damage rolls it makes. It must keep the new rolls.



Bove is the Storm Lady’s right-hand minotaur who travels through the different stages of the Maze to ensure that none of its prisoners come close to solving its riddle. In addition to the stats normal for a minotaur, Bove is usually under the effects of a potion of lightning resistance. He also has wields the storm sickle.

Thunderous Flail

Weapon (sickle), rare

This sickle sparks with electricity as beads of water form and drip from its blade. You can make a ranged attack with this weapon instead of a melee one whenever you take the Attack action by slashing through the air to send out a blade of storming wind. Ranged attacks with the sickle use Strength as your modifier for its attack and damage rolls and have a normal range of 20 feet and a long range of 60 feet. Any target hit by an attack from the sickle takes an extra 1d4 lightning damage.

The Storm Lady

The Storm Lady is a high-level Storm Sorceress who uses her power to fuel her maze and the Tempusfuge within. Because of her connection to the Tempusfuge, she is effectively immortal.

Ideal. “Born of lightning and thunder, I am power incarnate. None can defeat me.”

Bond. “The Tempusfuge is the source of my power. I will kill any who seek to unlock its secrets.”

Flaw. “I have grown lax over the years and do not recognize true threats when they appear.”
