After the initial phase of the battle, the game shifts into Duel Phase. During this phase, fighters are restrained to a two-dimensional space, similar to the play style of other fighting games such as Tekken. To accommodate with the reduced moving space, fighters have access to more moves during this phase.
The goal of Duel Phase is to damage the opponent as much as possible by using a variety of moves initially not available to Field Phase. While this phase allows the fighters to perform stronger attacks and combos, it is generally much riskier than the former phase. A fighter who shifts the game back Field Phase is rewarded with an increase in their Support Gauge.
Unlike in Field Phase, all attacks performed by the Y button become Weak or Light Attacks, whose moves prioritize speed over damage. All attacks performed by the X button become Strong Attacks, whose moves focus on damage output. These moves can be performed in tandem with the directional buttons as well.
Main article: Stance
Because of the two-dimensional environment, fighters can only move forwards or backwards. The up and down directional buttons changes the Pokémon's stance instead, a mechanic exclusive to Duel Phase. Different Pokémon have different abilities in either stance. Generally, standard moves performed in high stance anti-air opponents or evade low attacks, while low stance attacks evade high stance attacks.
Phase Shift Points Edit
A mechanic hidden to the player is the Phase Shift Point system. Each fighter is internally assigned with an integer, initially at zero, that causes a Phase Shift once it reaches 12. Every move that hits a fighter increases their Phase Shift Point by a certain amount. Managing Phase Shift Points is important for optimizing combos, as the latter can be cut short by a Phase Shift.
