The Geomancer's Brush is a craftable Hardmode magic weapon. On use, causes the user to paint a magical sigil over the course of 0.75 seconds at the cursor's position. There are three different types of sigil that can be painted, each performing a different attack when an enemy enters proximity of it (indicated by a colored ring around it that fades over time). By right-clicking, the player can alternate between the three sigils.


Type Attack

  • Although the Geomancer's Brush produces a colored blur effect similar to the Arkhalis, it does not deal damage and is instead purely a visual effect.
  • If the Show Donator Item Color configuration option is disabled, the Geomancer's Brush will have a rarity of Rarity Level: 4 instead of the standard Rarity level: Donator.
