Glumroth belongs to the Void class. This cute little guy doesn’t do much at the start of battle thanks to its low Speed (made worse by one of its passive skills!), but is capable of gaining a huge damage advantage over his opponents thanks to his many sources of Power gains and his ability to decrease his enemies’ Defense.
Glumroth also has a few very powerful passive skills, including some that deal damage to all monsters on the battlefield (including your own monsters!) and healing himself based on the number of monsters damaged. Perhaps most importantly, Glumroth has the unique ability to disable a piece of an enemy’s equipment – this is especially useful when an enemy is wielding a piece of unique gear that grants it an annoying, powerful skill.
