Sup yall

Soo one thing i found a GMBow with 3 to bowa but i found it in chaos hell so if i do the add sockets will it roll 4 5 or 6sockets? And is the grand matron bow base the best overall?

Also the skill and stat spec obviously lots of dex any into vita? As for skills i cant remember much. So if i have razortail should i still pump pierce up to 75%?

Literally any information i appreciate as i only did a bowa like 5 years ago
