Make Things Difficult for Your Enemies with the Unofficial SABOTEUR Subclass
The Artificer was released as part of Eberron: Rising from the Last War earlier this week and fans are already at work creating unofficial subclasses. Melissa Doucette has created the Saboteur subclass for the Artificer which is designed to, you guessed it, sabotage things. Your spell list includes counterspell, find traps, bane, and a few others which are perfect for that very purpose. You can also create arcane traps and eventually you get the ability to make a plethora of saving throws with advantage.
You can purchase The Saboteur from DMs Guild for $1.
