My 6 year old sister love to play diablo, but she doesnt know how to play haha, she can only use two skills at most, i made a mage build with the vyr set that was pretty easy for her to play, she only need to spam arcane torrent and use archon to fight elite mobs, the others skills she doesnt use haha, so i put skills like energy armor and magic weapon that last a long time and i can activate for her, then give her the gamepad and let her spam her arcane torrent and archon, but now she wants to change the build, i want to know if there is any good build that can let her play using few skills and still get a good result.
*sorry if i posted on the wrong place, i wanst sure about where to ask, and sorry about the bad english.
"Easiest" is a broad term. In terms of being able to be played with as few buttons as possible, I would recommend a multishot demonhunter (with the unhallowed essence set). Depending on the build and items, you can get by only using vault (for movement) and multishot with the occasional generator (but with enough gear, you won't really need that second focus/restraint stack)
You gotta toss in Sunwuko Wave of Light in this list. Assuming you can farm all the necessary pieces for your sister, once she is set up, it's pretty much one click and entire screens of enemies are gone. Epiphany and Inner Sanctuary are honestly unnecessary unless she wants to push harder.
