Code
§20B1

§20B2
Source
summon

Give the nearest creature of a given description, so long as it is within 100km of the invoker, a desire to travel as quickly as it is safely able to the point the invoker occupied at the time of invocation (fixed).

Planar Summons

Intensity
2
Code
§20A3
Source
summon

Give the nearest creature of a given description, so long as it is in the same plane as the invoker, a desire to travel as quickly as it is safely able to the point the invoker occupied at the time of invocation (fixed).

Animate Dead

Intensity
2
Code
§20A4
Source
summon

Animate the corpse or skeleton of a DT1 or weaker creature (by summoning a trivial demon for the purpose) as a zombie or skeleton respectively (see the creature descriptions).

Note: the figures given (under Creatures) for zombies/skeletons assume that (near-)human skeletons/corpses are being animated. If the original creature had DT d, then the skeleton/zombie will have DT d-3 / d+1, and DC d+1 / d+2. The GM may wish to make special allowance for non-humanoid skeletons/zombies.

Also note that skeletons and zombies are intrinsically hostile to any living creature (including their summoner). Corpses/skeletons without intact heads/skulls cannot be animated.

Named Summons

Intensity
3
Code
§20A4
Source
summon

Give a specifically designated creature (one whose personal name and appearance can be uniquely specified), wherever it is on whatever plane, a desire to travel as quickly as it is safely able to the point the invoker occupied at the time of invocation (fixed).

Dismissal

Intensity
3
Code
§20A5
Source
summon

Dismiss a creature which fails an EF 7-2B WP roll (use magic resistance lacking a WP value) of DT ≤ ⌊A/2⌋, giving it an overpowering urge to return to its "home" (plane, lair, or whatever). If it has no means to do so, then it will be unaffected. (Range: 20m.)

Designer's Note: so, in some sense, this effect is no good against low- or high-end demons — the former can't and the latter won't — but good against the mediocre ones, and other summoned critters of course.
