sorry for spaming the submissions so much but first time I have been queing since I got acc 
Dont know how well knowed this, but I have killed so many that havent knowed how to fight in the water I thought I should post this....
Since most ppls swim below the surface just so u cant shoot em with arrows or magic... but if u load the arrow/spell when u are up at the surface u can get below and shoot... after u have release the shoot u have to go back up to surface and "reload"
hope this helps someone that didnt know... (imo most ppls dont know this)
