1. portal warpstones
Syntax: cast portal <target>
The portal spell is similar to gate, but creates a lasting one‑way portal to
the target creature, instead of transporting the caster. Portals are
entered using the 'enter' command, as in 'enter portal'. Portals cannot be
made to certain destinations, nor used to escape from gate‑proof rooms. The
portal spell requires a warpstone in order to function. This stone can
either be held or simply be located in the caster's inventory. Once you
cast the spell, the warpstone will be used up and disappear.
2. enter portals
Syntax: enter <portal name>
Enter can be used to walk through a portal. A portal is a doorway of sorts
which leads from your current location to elsewhere. Often times it's a
one‑way trip. It is possible to 'look in <portal name>' to see what lies on
the other side, although some portals have random exit points and so looking
in the portal twice to be sure of where you'll land is always a good idea.
