Quick Reference

Why Morveth’s Treasure Gun is Worth the Grind?

Morveth’s Treasure Gun stands as a crucial stepping stone in your Abyss progression journey. According to comprehensive analysis from multiple sources, this weapon offers exceptional value with its high damage output and relatively low cooldown time. When compared to its predecessor, the Magroot Gun (190 damage, $47,500), Morveth’s Treasure Gun delivers 50 additional damage for just $35,000 more – making it an excellent investment for serious players.
