The Banshee periodically attacks nearby enemies. Instead of a Mana Power-up, the Banshee uses Shriek and her attack radius becomes unlimited. Inactive Banshees periodically lose a merge rank and give a Fear Orb to a random active Banshee, increasing that Banshee's damage.
Banshee damage is increased by 15% for every Banshee in the chain. Maximum damage is reached with 7 Banshees.
If there are more than 4 Banshees on the field, Banshee attack radius is increased by 30% and damage by 35%.
Using an active ability has a 10% chance of increasing the merge rank of the lowest merge rank Banshee. The chance increases by 5% for every Banshee on the field.
If there are 1 or fewer Banshees on the field, merging units results in a new Banshee. Damage of all Banshees is increased by 10%.
Movement speed of monsters within the Banshee's attack radius is reduced by 30%. Armor of monsters within the Banshee's attack radius is reduced by 15%.
Monsters within the Banshees' radius die at 25% health, while bosses die at 20% health.
Banshees have a 5% higher chance of a critical attack. When using Shriek, bosses lose their abilities for 4 seconds.
