Heroes: The New Battle Specialists

The time has come for a smarter, more strategic brand of heroes. Rather than being foolish, hulking brutes, the King and Queen are now much smarter on defense, have distinct strengths and weaknesses, and their abilities are more important than ever.


✔ The heroes have gotten sick and tired of being lured out and squashed in the edges of the map. Now, they only attack targets in a limited territory around their platform and will retreat if they get drawn away too far.

✔ Both heroes now get a damage increase and recover health when activating an ability. Use the damage boost to get an edge over defending heroes, or the healing to save them from the clutches of defeat!

✔ Hero abilities now improve much more significantly with each new ability level and summon more supporting troops than before. The best way to make your hero stronger when attacking is to increase their ability level!

✔ Hitpoints and damage for the Queen and hitpoints for the King have been slightly increased at lower levels. However, hero hitpoints and damage have been decreased at higher levels in order to balance heroes on defense and allow for stronger abilities.

✔ The effect of Rage Spells on Heroes has been reduced to put more emphasis on the skillful use of hero abilities. For the Queen and later levels of the King, bonus damage from hero abilities will far exceed bonus damage from Rage Spells. As before, Rage Spell bonus damage and hero ability bonus damage will not stack (the greater of the two takes precedent).

✔ Heroes now specialize in a certain role:


Barbarian King: The Tank Specialist

✔ His damage has been reduced, but he now can heal himself greatly when using his Iron Fist ability.

✔ The Barbarian horde summoned by Iron Fist has doubled in size to cause even more mayhem!

✔ Use Iron Fist at the right time to help the King take more damage than he ever could before!


Archer Queen: The Damage Specialist

✔ Her hitpoints have been reduced in later levels, but the Queen now gains a tremendous damage boost while her Royal Cloak ability is active.

✔ The duration of Royal Cloak has been greatly increased in lower levels to help make sure the Queen has enough time to land her most powerful of shots.

✔ Use Royal Cloak at the right time to help the Queen hit important targets harder than she ever could before!



Jump Spell: Control the Battle Flow

The Jump Spell used to only affect troops it landed on, often leading to disappointing results. Now, the Jump Spell influences all troops in the battle. Masters of the Jump Spell will be able to direct their melee troops like never before!

✔ All troops you deploy can take advantage a Jump Spell, even if the troops are not directly hit by the spell.

✔ Casting a Jump Spell will now cause troops to redirect themselves immediately if it opens up a more advantageous route close by.

✔ The Jump Spell area has been slightly reduced to allow for more precise control of the spell.


Valkyrie: The Wild Whirlwind

The Valkyrie rarely used to put her area-damage to any good use. Now, that has changed in a big way, and you might be shocked by her effectiveness in battle.

✔ Valkyries now charge around and position between pairs of buildings to find the best spots to attack.
