The Grand Warden is based on both the Wizard and the Healer , similar to how a Barbarian King and Archer Queen resemble a Barbarian and Archer respectively.
He is automatically summoned once the Grand Warden Altar is constructed, which costs 6,000,000 Elixir and is available at Town Hall 11.
The Grand Warden initiates a range of his passive Life Aura upon deployment, which grants units with additional health. Any unit to leave this range is stripped of the ability, unless they re-enter it.
The level of this passive ability is increased once every level, unlike his active ability which is increased every 5 levels.
The Grand Warden is the third hero in the game, being weak in physical strength but extremely powerful in support. His active ability, Eternal Tome renders all friendly troops within his aura invincible to damage for a short time.
Eternal Tome is upgraded every five levels that the Warden increases. The ability’s duration increases by 0.5 seconds per level.
During defensive mode, he will turn into a stone statue and act as any other defensive tower while using his Life Aura to provide a health boost to defending troops and buildings.
The Grand Warden will attack the building being attacked by the highest number/troop space troop, and will continue to attack that building until it’s destroyed.
