A couple of questions

Hey all I played PoE, but never really asked these questions, so I am going to ask them for PoE 2.

Question 1: Should I buy weapons and armor and stuff from vendors, or just the gambling vendor?

Question 2: Should I use stuff like transmutation orbs when I get them or is there a crafting thing like in PoE that I just haven't unlocked yet that I should save them for?

Appreciate the help <3

Both, but if i have tons of gold at the start of this game i would gamble hoping for nice rare item or unique that helps to ease leveling

since gold is not easy to collect early game, best stick to vendor for any upgrade
