Sometimes a elemental wall rune (like energy wall or poison wall) casted stays on a straight line, and sometimes stays on a weird form like the screenshot below. I want to know how to use these runes.

Excellent question. Do you mind if I add on the title that you are asking more specifically about wall field runes?

no problem, my english is too bad x.x

Answer 1

its not necessary to cast a elemental rune in a straight line in a position of the player, in the case i cast a energy wall in 1 sqm in the right of the straight position.

searching deep i realized that are a lot of sqms with we can cast a wall rune in straight position, and i listed this points.

In all of this points you can cast i straight wall.

wow, what a discover! Thanks for letting us know about it! First time that someone tells me about that!

Answer 2

If you throw it in straight line it will be displayed as  a straight line , example:

In the case of your photo the rune was probably throwed like this:

As you see in that case you are not throwing the rune in straight line, in that case if you throw it on diagonal the rune will display on diagonal. 

Note: Energy wall cannot be throwed on yourself like other runes.

Nice! If you want, pointing out this on your main answer would be interesting! And thanks for using screenshots, they look  very explanatory and easy to understand :)

Thank You XD now all runes stay in right position, the energy walls have a longer sqms than fire wall.
