PoE Calluhboose builds

Yo! So I decided to go for a Lightning arrow MF character and I am having a blast so far, the currency is starting to come in. I am a bit lost though where to upgrade the character to next, I am aware there are probably a million flaws with my character but I am kinda new to this so feel free to criticize.. I would love some input though as to what you'd invest into next, might have missed to config something in pob but I'll link it &x200B;
