Since the flight spells is gonna get removed(Vetex has made a realy good point for the reason) and everyone still want them, while trying to sleep i got an idea
This is me talking at 2am
Ima explain it better, the flight spell should become a spell that make you go faster underwater and make your oxigen bar larger, this is slower then boats by around 1/3 and its not worth using to move from island to island.
-Why would someone use this?
to get chests and events underwater
-it can be abused to run in the ocean.
it has a preparations just like the flight and if you get hit it stop.
-The fly its not a good way to move since its just a propulsion so you do nt have much control.
don t make it exactly like a flight so a propulsion that push forward the point you are aiming but something more controllable like with WASD.
About diving spots, now we have a way to explore under water now we need alot of things to do down there too so other then chests alone make some kind of puzzles, like the underwater maze, but randomly generated if possible and other fun activities.
The rest of the idea its up to you and vetex so write down here what its right ,what is wrong and obvs if you have more ideas i would like to know what you think.
