Mauler

The Mauler is a mini boss that spawns in the Sulphurous Sea at any point in the game. It swims peacefully until the player comes near or hits it. Once it detects the player, it swims extremely fast towards them while also shooting quick bursts of sulphuric mist. Occasionally, it releases a large ring of sulphuric bubbles and mist from itself, which is difficult to dodge unless the player is reasonably far away.

If the Mauler is out of the water for too long it will explode, leaving no loot and potentially killing the player in the process.

It can be detected with the Lifeform Analyzer.

On contact, the Mauler inflicts the following debuffs:
 * Venom for 5 seconds.
 * Bleeding for 5 seconds.
 * Feral Bite for 5 seconds.

Additionally, the sulphuric bubbles and mist inflict Venom for 2 seconds.
