i will try to explain as well as i can : a spell can be double checked or not, depending on if its a defensive spell or offensive spell.
on phoenix right now, defensive spells are being double checked, it should not happen. like you start casting a heal or a buff and the target goes behind a wall or a door, the spell should still go off. on the opposite, in the same case if it was a mezz/root/nuke, spell should not go off. i made a small video to make it easier to understand
