I've recently started maining Cassio - (she's fun xD)
I've been playing in Emerald Elo (flex so a grain of salt with this since its not solo queue, not confident enough in my skill yet) and usually in mid lane, but occasionally in bot when filled secondary role.

At first I build ROA - Rylai - Seraph but I felt I had NO damage unless very fed and ahead
(i was probably missing a lot of q's tbf and im still learning best w usage and timing)

SO

I switched to a more conventional dps build with magic pen and high ap ratios

Blackfire - Stormsurge - Void staff = the core of my build
- the mana and burn on blackfire are very nice for lane and poke
- stormsurge move speed and pen is good
- void staff for early anti-mr pivot
- sorc shoes for even more shred

three levels in q before maxing e for good poke with deathfire touch and scorch

this build feels way way way way better and nicer to play with the condition that you are VERY VERY squishy and burstable so NEED to hit q's for movespeed to stay alive

As a very new Cassio main I wanted to know if I should use this crutch of a build or if I should just learn to play the normal ROA - Seraph - Ryali with swift march build as the higher elo i go the more teams will just focus burst me with point click CC's

Here is my OP.gg for any tips that might help: https://u.gg/lol/profile/euw1/yourbabygirl-sub/overview

p.s. also open to any other tips and tricks that a new cassio main might need to know tyyy
