There will be many locations in Crimson Tactics that will have waterbodies - some shallow, some deep. Gameplay and visuals will change when these geographical features are present in different locations.
Shallow Water
All characters can move around in Shallow Water. Their feet will be slightly submerged in the water and their accuracy as well as agility will be somewhat decreased.
Deep Water
Characters cannot walk over Deep Water in normal circumstances. The only way to do is by applying the ‘Water Walk’ buff to characters. Characters that have used Water Walk will not have any part of their bodies submerged under the water, though their accuracy and agility will still be decreased.
Falling into Water
If characters are pushed onto a Deep Water tile and they do not have the Water Walk buff, they will immediately drown and be eliminated without any chance of being revived.
PS: The Water in this particular level is all Shallow Water. Some tiles have been modified to demonstrate the Deep Water Gameplay.
