There are several beginner builds in that section of the forum, including a pet Conjurer that Maya wrote. All beginner builds are aimed at easy to obtain gear, levelling suggestions and devotion paths to take.
Dark One is your endgame. This set is target farmable and you can get it in a few hours or less (search for “Lokarr quest”). Other items can be gotten easily once you get in Crucible farming shape which - once you get Dark One - is more than possible with faction gear and random non-BiS drops. It’s a vitality caster, currently one of the strongest builds in the game, able to clear all content with no exceptions.
Search “conjurer of the dark arts” - a Mad Lee build, top quality.
after all i decided to try pets, not sure if its good idea or not(dropped schematic for set helmet for pets). lvl 70 atm, just switched from lightning, dont have a lot of gear still but i want to farm bismel rep now for weapon schematic and then propably will be much better
okay lets say i want to farm this dark one set(im progressing elite now), should i farm it first at veteran and then another one one elite? or try to do this at elite even if it can be super hard?
Playing a conjurer, going Vitality without pets (e.g. Vitality Totems + Devouring Swarm + Doom Bolt or whatever people use to level) is the current “conventional wisdom”.
Otherwise, double down on pets, maxed bird base skill, decent bird aura and bird attack spell, nothing in mend flesh, and maxed briarthorn with briarthorn aura would be my way to go. It’ll give a massive amount of durability to your pets (Aspect of the Guardian 12/12 and Emboldening Presence) and you.
