ToME: the Tales of Maj'Eyal

With the addition of many, many steam-draining sustains in Embers, I think it would be a useful option to sustains to deactivate on rest, in the same way Osmosis Shield and Rain of Fire. Obviously this is less important for steam than vim, but it could still be a useful quality of life feature. Ideally this would not be exclusive with the auto-use bindings.

if it drains faster than it regenerates, it will just turn off, and then regenerate to full.

also, gues what?
there is a talent, which normally takes a turn to deactivate.
but because it already auto-offs, if you click r next to an enemy, it turns off without actually passing any time.

unless it was fixed.
