Eternal Tome: Max Levels and Upgrade Statistics – Clash of Clans

Eternal Tome is a common type of hero equipment available to the Grand Warden in Clash of Clans. Upon reaching Town Hall 11 and unlocking the Grand Warden, you automatically gain access to the Eternal Tome. The Eternal Tome provides the Grand Warden with an “Active Ability” that triggers when he uses his special ability.

When activated, the Eternal Tome renders all troops and the Grand Warden himself invincible to all incoming damage for a few seconds. The duration of ability is linked to the level of the equipment.

Eternal Tome Max Levels

Here are the max levels of Eternal Tome equipment:

• Eternal Tome has a max level of 12 at TH11.
• Eternal Tome has a max level of 15 at TH12.
• Eternal Tome has a max level of 18 at TH14.

As Eternal Tome is a common type of hero equipment, it can reach a maximum level of 18, similar to other common equipment. The first 12 upgrade levels for the Eternal Tome are available at Town Hall 11. Subsequently, three additional upgrades become available at Town Hall 12, bringing it to level 15.

The final three levels are reachable at Town Hall 14. There are no upgrades for the Eternal Tome at Town Hall 13, Town Hall 15, and Town Hall 16. Its upgrades require Shiny Ore and Glowy Ore, as Starry Ore is reserved for epic types of equipment, and the Eternal Tome falls under the common category.

Details

Ability Type: Active (triggers for all troops within the Grand Warden’s aura upon the activation of his ability)

Equipment Type: Common

Available at: Town Hall 11

Unlike other equipment available to the Grand Warden, such as the Healing Tome and Rage Gem, which usually have multiple statistics linked to them, the Eternal Tome has only one statistic: “Ability Duration.”

This duration determines how long the troops inside the Grand Warden’s aura will remain invincible to damage when his ability is activated. These troops stay invincible until the duration runs out, even if they are no longer within the Grand Warden’s aura.
