Storm Box on left mouse

[eisprinzessin]

Left click restrictions

Generally when a skill can’t be bound to left-click, it is because it would interfere with moving around (ex. Aether Ray or any ground-targeting ability)

This does not seem(?) to apply to Storm Box but maybe this does:

Bloody Pox to LMB?

I have not found an explantion, but at least a confirmation:

ArdjayTw :is it possible to make it so that curses like blood pox and ill omen be put on left mouse button plz @CrateEntertainment ?
[Zantai:] That is not possible with this engine because the left click must be available for moving around and those skills target enemies.

The quote is from a Twitch stream chat protocol from 2018.

In any case, there have been several requests for Storm Box. I bet Crate would have fixed that by now, if it was possible.

There is a workaround though:

More skills for mouse 1

Believe me, SBoE-builds are so much fun when used with LMB (makes targeting much easier). I do that via script.

More skills for mouse 1

Whenever I hover over an enemy, I serve him SBoE automatically.
Very convenient with high casting speed.
