Astral Spells

[Geras]

How feasible code wise would it be to implement a couple of spells that can be invoked (but not evoked) in the astral realm? There are a few that could be useful. I was thinking a spell to create a gate node on demand, or to get past closed doors, or to teleport one's avatar to another location would all be useful. Perhaps one astral spell per element/moon pair?
