Explosive/Shock Gemling

Hello,

I'm having lots of fun playing 1h a day in average and 2h in the weekends due life. I have 2 chars. This is one of them. The build is pretty solid. I recently completed my 4th ascension on trials of chaos.

I can do all content, including citadels but I feel that I'm a bit squishy. How can I make the build stronger? Attached the skills, items and other details.







Any feedback is warmly welcomed
