General Tips

  • This trial is something you should attempt close to the end of the game. Before you begin to even think about trying this trial, you should have all the nail upgrades and nail arts, along with as many mask shards, vessel fragments, charm notches, and charms as you can find.
  • You want as much health and soul as possible. You should also have every ability and spell available. At the bare minimum, you should have the Monarch Wings and the Shade Cloak.
  • Heal as much as possible during the lulls between waves. If you keep easily dodgeable enemies like Shielded Fools and Sharp Baldurs alive at the end of a wave, it will delay the arrival of the next batch of enemies and should give you enough time to recover health. Definitely make sure to heal before Wave 14 starts as you won't get an opportunity while the spikes are up.
  • Some good charms to equip include Mark of Pride and Longnail, as being able to strike enemies like the Brooding Mawlek from a distance will make your life easier. These are also good during Wave 14 and 15, as they'll give your nail jump attacks extra range.
  • Quick Focus can help you heal faster, and Hiveblood can passively heal you when you don't have a chance. Charms that help you gather soul like Grubsong and Soul Catcher can make sure you have enough soul to heal and use spells. If you are going to use spells, equip Spell Twister to reduce their cost.
