Runes and essence
Grow high-level Runes with Spica Essence
Spica Essence offers a route to extend the growth ceiling of a developed Rune beyond its existing level limit.
WHERE & HOW TO FARM
Grow high-level Runes with Spica Essence
Agony Wave reward chests for Spica Essence; Rune growth interface for use.
Before you go
- Reach Agony Wave access and obtain an Agony Key from a Chaos Dungeon boss.
- Have a Rune at level 31 or higher for Spica use.
- Obtain Spica Essence from available Agony Wave rewards.
- Select a Rune you expect to keep using.
Farming steps
- Choose a core Rune that remains relevant to your build and verify its current level.
- Run Agony Wave and defeat bosses to collect Agony Shards.
- At Agony Terminus, inspect the reward chests and select one that offers the desired materials if shown.
- Check inventory for Spica Essence and read its current tooltip.
- Open Rune growth and select a Rune at level 31 or higher.
- Review the warning that the result may increase, remain unchanged, or decrease the Rune level.
- Apply the Essence only if each possible result is acceptable, then inspect the Rune's new level.
- Use Spica on a core Rune rather than a temporary leveling skill, because failure can lower its level.
- Check chest contents before spending Agony Shards; do not assume every chest contains Spica.
Repeat, collect and use
Repeat while you obtain Spica Essence and have eligible Runes. The use is stochastic; Agony Wave rewards and chest contents are not a guaranteed fixed quantity.
Common mistakes
- Trying to use Spica on a Rune below level 31: level the Rune first and confirm eligibility.
- Expecting every use to increase a level: growth, retention, and failure are possible outcomes.
- Treating Spica as a reversible craft: consider the possible level loss before applying it.
When to stop or switch
Stop once the Rune reaches your target level, or pause when a possible level loss would set back a more valuable build goal.
