This game is really addictive, especially the rune system, where you slot your skills into a grid together with their upgrades for maximum efficiency. And the game overall far higher quality than I expected, with decent voice acting and cut scenes. My only gripes are that there doesn't seem to be a way to grow your runes to your current level without selecting each one individually, and I as someone who prefers to play single player, I personally dislike the always online requirement.

I'll been searching for new games that can replace Diablo immortal, It's also reminds me of Lost Ark in lot of way. This game does it for me for time being(No silly auto combat)you actually have too pay attention. story is great, an combat is lil to easy (I hope gets more difficult later on likes Hell mode ect) but I am early in the game anyway.

I won't lie, I'm addicted and I love it. Some things I hate, The UI isn't resizeable, so despite your choice of method to play, still expect to struggle to see. There is embedded autoaim, so if u love range skills, they still rock, but it gets really annoying. Idk, I'm only a few days in. It just needs more settings, this game has insane frikan potential and I'm in love, it just needs more love on the side of more settings so it's better for pc and mobile. ADJUSTED from 4 to 3 stars
