I'll fix GiveEnergy working with Sleep too.
Unfortunately, if I switched to "g" to pick up for Brands, I wouldn't be able to show the tooltip of the Brand automatically like I do now.
I'll see if I can think of another way to address the issue, but I think showing the tooltip is a good thing, even at the (for now) cost of the prompt.
The stat-stacking for ghosts is almost exclusively limited to players: demons, even modified ones, will almost never have stats stacked enough to actually trigger the effect. That *is* a powerful Brand, no question... but "no passive abilities" is a pretty hefty restriction, as you noted.
The stat-stacking is really only meant to rein in attempts at 5 per level Strength or 5 per level Magic nonsense, or people who get crazy lucky with Essences early game. It isn't something most builds will trigger.
