I was doing duo sims and I wanted to try and transition into solo spark, but my damage and survivability are wretched. Is anyone able to give me a hand?

you provide no pob no context nothing and ask for help, you might be too dumb for poe

Send me a pob and I will have a look when I have time tomorrow.

or maybe hes not as experienced as you
given that you need some sort of college degree just to play the game or something as it it far too bloated with content,
i mean the game can take years to master fully because theres so much involved.

Yeah next time I ask for help with anything I'm just going to not give anyone the ability to help me.

given the amount of information, best advice I can provide for now is

slot Spark gem in your sockets and try linking it with a few supports
