Brooding Mawlek

Attacks
Will slash the player if they get to close to it's left or right. Also shoots small energy balls at the side of it the player is on. Its strongest attack is shooting a massive wave of energy, that covers the whole side of the room the player is standing on.

Tactics
You may try slashing at the sides but unless you have reach enhancements, it will often strike at you when you hit it.

The best bet is to jump over the Mawlek and slash down at it while jumping over it.
