Corrupt Master of Grounding
The Corrupt Master of Grounding (in-game name Korruptoitunut Maadoittajamestari) is one of the many Corrupt Masters. It takes the appearance of a humanoid with a television for a face turned into pure static.
Behavior
The Corrupt Master of Grounding casts fast-moving homing projectiles that inflict the 
Neutralized spells status effect for 20 seconds. Any spells cast by you will instantly fizzle out, while explosive spells will detonate immediately. This effectively negates all of your offensive options aside from kicking and throwing objects.
Additionally, if the player gets too close and the master has visual line of sight to the player, they may cast a beam which inflicts the 
Shield Instability status effect for 15 seconds.
Like all Corrupt Masters, they will generate a temporary shield to protect themselves upon taking damage.
Combat Tips
- As with all Masters, exercise caution and focus on avoiding the projectiles. This is easily done by constantly moving perpendicular to the enemy's aiming trajectory (which usually means levitating up or falling down) and staying at a medium distance.
- Try to keep your distance from Corrupt Masters of Grounding, as while plasma shields are an excellent tool for keeping yourself, they'll become useless if you get within range of the master's beam attack.
