"This veteran battle-scholar seeks out groups of friendly troops to fight behind and boost with his Life Aura, and assumes the form of a tower on defense. Attacking, he can walk over walls or fly high, and can make nearby troops immune to damage once his Eternal Tome ability is unlocked!"
The Grand Warden is a single target unit unlocked at Town Hall level 11.
He can be set to Air or Ground mode, which he flies in Air Mode and walks on Ground Mode.
However, he can fly over walls regardless of the mode, but will attack a wall piece if many other troops are attacking it.
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.
The Grand Warden is the third hero in the game, being weak in physical strength but extremely powerful in support.
The Grand Warden's 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.
The Eternal Tome ability negates damage, but not other effects. For instance, the Spring Trap will still bounce troops.
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 Heroes.
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.
Use the Grand Warden in Air Mode if you are using an air attack so he does not take damage from ground defenses (as they are not distracted by other troops) and Ground Mode when using ground army as he will not be targeted by the Air Defenses.
Only set him to Air Mode if you are using an Air Attack, as without distraction troops, he can be killed by a Seeking Air Mine regardless of level.
Use the Eternal Tome ability near the core so your troops can get through the core, where the most damage usually is.
The Grand Warden goes where other troops go, so he does not need funneling.
However, the other troops need to be funneled.
He will follow the troop with the highest housing space or the largest mass of troops, so bunching up troops with the Grand Warden is crucial to getting the most out of his abilities.
However, do not bunch them up too tightly, as the Life Aura is big and the troops will take a lot of splash damage from other defenses if they are too bunched up.
If the Grand Warden is positioned correctly, he can defeat an enemy Barbarian King without being attacked.
He creates a buff to boost defensive troops, heroes, and skeletons. It is recommended to place his alter near structures that will receive the benefit such as the Clan Castle, or other Heroes.
When defending against an enemy Grand Warden, make sure you set your Inferno Towers to Multi Target, as he is often behind other troops so few defenses can hit him.
The Grand Warden goes through minor visual changes at level 10.
Initially, he has purple facial hair similar to the Archer Queen, and his facial characteristics remind those of a Giant. He wears white and purple robes along with a short cape. His eyes are of different color, one is white with a little pupil and the other is a normal one with a blue iris. There is a gold trim on his collar at the neck and he wears a white crown-like decoration on his head. He also holds a thick book and a long wooden staff with a magical crystal held on top.
At level 10, his white antler crown becomes golden.
The Grand Warden was initially revealed as the new hero for Town Hall 11 at ClashCon 2015. However, only a silhouette of him was shown.
In the sneak peeks showcasing him, his hitpoints at level 20 were 2,000; however it was changed to 1,500 in its release.
His beta ability colour was orange, but was later changed to yellow when released.
Each successive upgrade of the Grand Warden adds approximately 2.16% health and 4.24% damage, but also adds a constant one minute to his total regeneration time. As a consequence, the Grand Warden's regeneration rate changes as he levels up. The Grand Warden's regeneration rate slows down each level, going from 2,000 hit points per hour at level 1 to 1,836.7 per hour at level 20.
