Possibly remove the xp cost of -teleport

[Nathan Brack]

All of the epic spells have a cost now (piety or spell component). -teleport was given an xp cost for its sheer utility (and I imagine the -teleport, -yoink combo), but since then unless I'm mistaken, teleportation has become a bit easier for everyone. So, maybe it's time to revisit the xp cost now that it costs spell components as well. Or not, depending on items I may be unaware of.
