Arcane Lake

A secret symbol left by Caryll, runesmith of Byrgenwerth.
This transcription of the Great Ones' inhuman voices ripples like a watery reflection.

This rune means "Lake", and those branded by it enjoy augmented defense.
Great volumes of water serve as a bulwark guarding sleep, and an augur of the eldritch Truth.
Overcome this hindrance, and seek what is yours.

Arcane Lake is a Caryll Rune in Bloodborne.


Arcane Lake Effects

  • Increases arcane defense. Arcane damage reduction.
  • Versions: +5% / +7% / +10%
  • Increases in Arcane defenses are visible in the menu
  • Runes stack additively, with a system of diminishing returns.
  • When a rune stacks, its effect is reduced by 10% of "what's already there".
  • For instance if Arcane defense is already 200, then the increase will be reduced by 20 Arcane defense.
  • +10% Arcane defense = +100 Arcane defense, which will become +80 if Arcane defense is already 200.



  • (+5%) found on a corpse in Yahar'gul, Unseen Village near the skeleton slug shooters, behind one of the burning corpses on the left wall leading down to the boss area.
  • (+7%) is found in Byrgenwerth to the left of the lamp, near the tree with the brainsucker.
  • (+10%) is found in Isz Root Chalice (random chance)



  • To memorize this rune, you must have the Rune Workshop Tool.
  • Arcane Lake + 10% - Chalice Glyph - ydknsnh4 (Layer 1)

            Help yourself. 1st layer boss is Man-eater boar, only just made the chalice.10% Arcane Lake rune in possibly the easiest FRC isz chalice. 73upz823. Two blobhy head mobs, one hunter and a brainsucker before opening the gate, rune is in bonus area after gate, one single zombie and one hunter (which you can just avoid, only bullets in his room beside himself).
