Also, another advice I’d give to every new player is to remap your movement keybindings asap, before you get used to the default behavior.
By default, you move your Character with W and S, you make it turn around with A and D and you ‘Strafe’ with Q and E (move sideways).
But, turning around using A and D is pretty inefficient. Your mouse can do that much better by just holding right click. Also, strafing is probably the most efficient way to move your character in combat situations.
So, the way I recommend is to go into Keybinding Settings and binding A and D for strife left and right respectively. This will completely removes the ability to turn your character around with the keyboard, but that’s okay.
This also frees up the keys Q and E, which you can use for your action bars. Q and E are so easy to press, that I always bind my most used spells to those buttons. Same with R, F, Z, X and C.
Once you do this, practice your movement for a bit. It might take some getting used to, but it will be much more efficient in the end.
You just hold the right button on your mouse when you need to turn your character around. You basically use your mouse to move, rather than to click on spells.
Since you will use strafing to move sideways, instead of turning around and walking forward, you will not need to turn your character around much.
For that reason, this pairs well with learning to use your spells through your keyboard, rather than clicking them. This is also a skill that will be greatly beneficial to you as you progress through this game. Most classes have several different buttons you need to press just to do your basic damage routine.
