Not Updated For Current Season
This is just a build I have used a couple of games and I have done pretty well especially late game.
For my move rotation I open up with transfusion and tides then go into puddle mode then by the time you pop out of your puddle your tide and trasfusion are ready again rinse and repeat.
Also late game when you have upwards of 3-4k health don't be afraid to stack your tides. Yeah they do a decent amount of dmg to you but my god do they hit the enemy team hard especially late game you may sacrifice yourself but in a team fight getting half of everyones life down by yourself with one move not to mention the others is pretty amazing. Until you get Rylais you are a little squishy so dont be too agressive until then. By late game you should be a healing damage dealing tanking machine so have fun.
Please feel free to leave comments and suggestions as this is a new champion. Have fun on the battlefield.
