Create Door

Regular
When cast at the near side of a solid obstruction (wall, hedge, cliff,
etc.), this spell creates a short-term, short-range gate leading to the other
side. The intervening distance is not actually traversed by the door’s users –
they are simultaneously teleported from the near side to the far one.
This spell has the advantage over Teleport of allowing access to places
unknown to the caster, as well as allowing him to transport more than
Heavy encumbrance.

Modifiers: The spell is at a -1 penalty per yard of obstruction thickness;
there is no penalty if the obstruction is half a yard thick or less. The GM
should not tell the player what the penalty is; he should simply tell him
whether the spell failed or not.

Duration: 10 seconds.
Cost: 2 per 10 square feet of door size. 2 to maintain. For reference, a
modern door is usually about seven feet high and three feet wide. A door
created for 2 energy would have to be significantly smaller.
Time to cast: 5 seconds.
Prerequisites: Teleport and any one “Walk Through” spell.

Item
(a) Staff, wand, jewelry, or writing implement (the latter is used to
“draw” the door on the obstacle).
Energy cost to create: 500.

(b) Portable door. It is activated (if its Power is above 15 after deducting the penalty
for obstruction thickness) after leaning it against the obstruction.
Energy cost to create: 500 per 10 square feet of size.
