Option to use spells that could be used at yourself or allies quicker by double clicking on it.

there's a self cast option already

for me its alt+cast = selfcast

wait. clicking spells? pls.

there are hotkeys for allied casts/self casts.

Do the following:

• Enable Quick Cast in your options
• Hover a character and press E to shield them. No clicking needed.
• Hold alt and press E to instantly shield yourself.

Finally your days of clicking will be over and you will cast twice as fast!
