Insomnia [Minor] by Iczer

'You are feeeling very sleepy....soon anyway'

The character can muddle with a target's brain, altering subtly the balance of neurochemicals involved with, and connected to sleep.

Range: 60 feet, but target must be within line of sight, or a 20 foot radius.

Duration: Varies.

Actions: One target requires 1 action, while an area effect requires 2

Saving throw: 16+ PE bonuses apply.

Effect: When first affected by this power, targets become a little drowsy. and a little less alert. reduce initiative by 1, skill performance by 5% and perception by 3.
if they fail their saving throw, their brain chemistry unbalances a little further. they undergo the equivilant of 2D6 hours without sleep.
The first time this happens there will be little noticable effect. after three or four uses, the target begins to be 6-48 hours behind on his sleep.
The effects of sleep deprivation vary from person to person, and are covered with some comprehensiveness in the heroes unlimited GM's guide (Page 46-47).
In summary: 48 hours without sleep: reduce spd by 20% -15% to skills -2 init -1 dodge 72 hours without sleep: PB-2 MA-2 -1 attack -4 init -2 strike and parry -3 dodge reduce spd by 40%, and the character is constantly exhausted.
4-7 days without sleep: halve PB and MA, limited to 2 attacks per melee, saving throws and combat bonuses are limited to +1. no initiative, reduce speed by 70%. extremely fatigued (resting for 10 minutes for every 5 minutes of exertion)
More than 7 days without sleep: One attack per melee speed is at 10% normal and skill performance is tanked (10% max) no combat bonuses. character hallucinates and will be forgetful.
9 days: Character simply passes out and remains that way for 5D6+30 hours.
because this power tinkers directly with the brain chemistry, targets normally resistant to sleep deprivation are still affected normally. Targets with alter metabolism can function normally through normal use of that power.
The character is immune to his own power, but needs a normal amount of sleep himself.
