Hydroxis R arcana caster
Hydroxis - Lv.120
Always stand in R-Drowning pool,
Cast Q on your enemies from high distance to amplify water dmg and keep them disabled.
Cast W on high distance to kill enemies trapped in Drowning pools.
Use E between drowning pools to keep your disance, move forward, refresh cds or skip to wherever you want.
I think this build is quite fun to play, as you dont just press one key and march forward. Actually you have to use all 4 keys, make decent use of them and still be quick in diving to other Drowning Pools if something dangerous is coming.
At least it would be fun if not for a very annoying bug with R3 which makes enemies move to some random points instead of Drowning Pool center. This makes them hard to hit with W and makes them disappear behind borders. You must then try to find them again to proceed.
As actually no one (except me) plays Hydroxis R-arcana, dont expect this to be fixed soon. I reported it 3 times already since R-arcana and nothing happened so far.
But except for this Bug, really fun to play.
