How to build a planar trader?

[Urpriest]

No he won't hand weave the cost :(

However 1/day version would cost "just" 24'000... still a bit too much.

If he isn't handwaving the cost of the amulet, why do you expect him to handwave the cost of the portal? If you've got sole access to a portal that's equivalent to owning it, and would cost 200,000gp out of your WBL.

If you want early planar travel and can't get it through Nomad, Artificer can do it at level 7 with a scroll of Plane Shift.
