Void Essence boss rewards
Eternal Core from Tiaggro
Farm a named endgame boss material for the specific recipe or progression step that needs it.
WHERE & HOW TO FARM
Eternal Core from Tiaggro
The encounter that lists Tiaggro, the Eternal Guardian, as its boss. Confirm the mode and its reward conditions on the encounter selection screen.
Before you go
- Unlock an encounter that explicitly features Tiaggro.
- Check the selected encounter’s displayed conditions for the Eternal Core reward.
- Bring a build able to clear the approach and defeat the boss.
Farming steps
- Open the relevant crafting or progression screen and note the Eternal Core requirement.
- Review available encounters and select one that names Tiaggro.
- Read that encounter’s reward and difficulty conditions; apply only the conditions shown there.
- Start the run and clear toward the boss while keeping enough health and damage for the fight.
- When Tiaggro appears, avoid incoming attacks and deal damage during safe openings.
- Defeat Tiaggro and collect the victory reward.
- Return to the fortress and confirm the Eternal Core count in your inventory.
- Use the Core for the recipe or progression step you identified.
- Match both the boss name and reward conditions to the selected encounter; a general Void Essence gate does not prove a Tiaggro-specific requirement.
- If the selected setup is unreliable, lower its difficulty where possible and build consistency before attempting a reward-gated version.
Repeat, collect and use
Repeat the Tiaggro encounter while the identified goal still needs Eternal Core. This is a repeatable boss farm; verify each reward and spend the Core through the relevant crafting or progression interface.
Common mistakes
- Assuming the Void Fields Curse gate applies to every Tiaggro encounter: use the conditions displayed for the encounter you selected.
- Entering a different boss fight: confirm Tiaggro is named before starting.
- Continuing after the requirement is met: check the next recipe or progression bottleneck and redirect the farm.
When to stop or switch
Stop when your intended recipe or progression step has enough Eternal Core, or switch if another material is now the missing requirement.
