How To Get Rune Of Tremendous Power

The Rune of Tremendous Power is one of the most sought‑after items in the world of Eiyuden Chronicle: Hundred Heroes. It grants a significant boost to a character’s attack and magic stats, making it a valuable tool for both early‑game progression and late‑game challenges. This guide breaks down everything you need to know to obtain the rune efficiently, from preparation to execution.

What the Rune Actually Does

When equipped, the Rune of Tremendous Power increases a hero’s base attack by a flat amount and adds a modest increase to spell potency. The effect stacks with other equipment bonuses, but it does not stack with duplicate runes. Because the boost is permanent, the rune is best saved for a hero you plan to develop into a primary damage dealer.

Where The Rune Is Located

The rune can be found in a specific dungeon called the Forgotten Sanctum. This area is unlocked after completing the main quest “The Shattered Seal” and reaching level 15. Inside the Sanctum, the rune is hidden behind a series of optional puzzles and a mini‑boss encounter.

Preparing For The Sanctum

Before you venture into the Forgotten Sanctum, make sure you meet the following prerequisites:

Having these preparations in place will reduce the number of retries and keep the experience enjoyable.

Step‑by‑Step Walkthrough

  1. Enter the Sanctum. Talk to the gatekeeper NPC in the town square after unlocking the area. Choose the “Enter the Forgotten Sanctum” dialogue option.
  2. Navigate the first corridor. The corridor contains three pressure plates. Step on the middle plate to open the door without triggering the poison darts.
  3. Solve the rune puzzle. In the central chamber, you’ll see four stone statues each holding a different elemental orb. Match the orbs to the correct statue based on the clues etched on the walls. The correct combination reveals a hidden compartment containing a Rune of Arcane Magic, which is useful for later upgrades but not required for the Tremendous Power rune.
  4. Defeat the Sanctum Guard. The guard is a mid‑level enemy with high defense. Use a hero with strong physical attacks and apply a debuff that lowers enemy defense. This battle is the most reliable source of the Rune of Tremendous Power if you defeat the guard without taking excessive damage.
  5. Collect the rune. After the guard falls, a pedestal rises, displaying the Rune of Tremendous Power. Interact with it to add the rune to your inventory.

Farming Strategies If You Miss the Rune

Because the rune is a single‑drop item, missing it on the first attempt can be frustrating. However, the Forgotten Sanctum can be replayed, and each run has a 20 % chance to respawn the rune. To maximize your chances:
