Make your boss fights more engaging.
The wondrous boss fights series looks at making the major boss fights of your campaign more memorable by providing a system where a powerful boss creature can activate at multiple points on the initiative tracker using a variety of actions with different energy costs. In many cases the boss creature will also have targetable hit locations that can be damaged or maimed to provide the players with an advantage in the fight.
Many aberrations have powerful effects linked to tentacles, eye stalks and other appendages, giving DMs plenty of choice on how to spend the creature's energy each turn. Conversely being able to target these locations adds a wealth of new options and solutions to the players.
