In previous Kingdom Hearts games, dodge would put you out of harms way and essentially let you dodge the attack. The exception was in Birth by Sleep. Dodge Rolling allowed to evade attacks completely, basically letting you be invincible as long as you kept mashing the square button. How does it work in 3D? Did it go back similar to KH/358/Coded or is it BbS? It is developed by the makers of BbS so they could have reused the mechanic.
