/**@file Greater Command
Enchantment (Compulsion) [Mind-Affecting]
Level: Cleric 5
Components: V
Casting Time: 1 action
Range: Close (25 ft. + 5 ft/2 levels)
Targets: 1 living creature/level
AoE: 30' Burst
Duration: 1 Round/level
Saving Throw: Will Negates
Spell Resistance: Yes

You give the subjects a single command, which they obey to the best of their ability. At the beginning of each round, the targets get a new saving throw to end the effect.

Approach - The target runs directly towards you for the duration of the spell.
Drop - The target drops what it is holding (This will not work on creatures that cannot be disarmed).
Fall - The target falls to the ground for the duration of the spell.
Flee - The target runs away from the caster for the duration of the spell.
Halt - The target stands in place and takes no action for the duration of the spell.
