I know there has been a thread about this spell before (and I read everything that was posted there), but I always bemoaned the fact that Gate spell for Ravenloft can only summon balor, and thus only evil-aligned truly use it. I'm aware that Gate spell is a DP-worthy, believed to be inherently evil spell since you're summoning an Outsider and that Outsider has no way out of Ravenloft, but Planar Ally and Planar Binding work the same way. I also do not think every character knows the fact that summoning in the Demi-Planes of Dread is a one-way street, and so some clerics and wizards will make this mistake.
Mechanically, I've seen a feature elsewhere where I could type /planargood, /planarneutral/ or /planarevil through chat commands to summon appropriate alignment creatures. Good summons a more powerful version of the Celestial Avenger (although it would be great if we could summon a deva, perhaps?), Neutral summons a White Slaad, and Evil calls forth a balor.
Thank you!
