Combination attack

A combination attack (連携必殺攻撃) is a technique performed by a group of Lilies, usually in order to defeat a powerful Huge. It is effectively not possible to defeat a Gigant-type or Ultra-type Huge without the use of combination attacks.

The most widely used combination attack in the present day, by far, is the Neunwelt Tactic and its variations.

B-type Armaments
Although B-type Armaments are used by a single Lily and not a group, they serve a similar function, and normally require teamwork on par with other combination attacks to avoid putting their wielders in extreme danger.

Kataphraktos Tactic
The Kataphraktos Tactic relies on a single Lily, called the "tank", deliberately placing herself in the way of Huge attacks to absorb their energy. The tank often uses a shield-like CHARM, and the entire team (which can be as few as 3 Lilies, or as many as 9) uses defensive Rare Skills such as Heliosphere to protect her.

Then, using a specialized CHARM OS, she channels a portion of the absorbed energy to her allies. The team can then create a spherical field around the Huge with this energy and cause an explosion within it, doing severe damage to them.

Kaiseizan favors the use of the Kataphraktos Tactic, and Sagami also teaches it to their Lilies upon request.

Other Combination Attacks
Rokuyaon and Sakuranomori also use combination attacks that differ from the Neunwelt.
