Hello there, I plan to start doing A1S with my FC soon and I'd like to know what's the minimum ilvl required to MT and OT it?

Also, I feel my vit is too low for having all those str acessories. Right now, I sit around 14700 HP unbuffed (ilvl 188), Also, all my points went to str instead of vit. If I swap it to Vit I believe i'd reac 15300 HP (16000 in a party).

What should I do? My HP is too low? Should I move points from str to vit?
Thank you in advance.
