Standing

When summoned, a player or mob is instantly transported to the cleric's
presence.  If the summoning fails, they may feel the effects of the attempt.
Casters cannot summon anyone much greater than himself.

   Summoning is considered an aggressive action, unless you are grouped with
the person.  A mob may well attack, and a player will need to forgive you
if they are not grouped with you.

Spell Potency Bonuses:

   Each tier of Spell Potency allows the caster to summon a target of one
level higher than they could before. At the highest power, clerics will
find their summoning range increased.
