Editing Gameplay/Stacking Mechanics (section)

== Attack and defense ==

Every line clear does two things, in order:

# '''Cancel''' garbage waiting in your incoming meter.
# '''Attack''' with whatever lines were not spent cancelling. That attack is sent to your opponent as garbage.

Each character has a '''damage table''' that sets how efficient each kind of clear is for attack and for defense. For example, a quad (4-line clear) with an attack value of 1.0 sends 4 lines at Phase 1. With a defense value of 1.0, the same quad cancels 4 incoming lines.

Characters are very different here. Some are built around T-Spins, others around quads or combos. You can view each character's full table in the character menu. See [[Gameplay/Character System|Character System]] for a summary.

=== T-Spins ===

Only T-pieces get spin bonuses. A T-Spin counts when the T-piece cannot move left, right, up or down after its last rotation. T-Spin Singles, Doubles and Triples each have their own attack and defense values in the damage table.

=== Perfect Clears ===

Clearing the whole board is a Perfect Clear. Some characters get bonus attack and defense on a Perfect Clear.

=== Passthrough ===

Some clears are marked as '''passthrough'''. A passthrough clear does not cancel anything. Its full attack goes straight to the opponent and your incoming garbage stays where it is. Examples are Taki's quads and Evangeline's T-Spin Triples.
