Greater Malison can only affect enemies, so if he's a party member, as you say, that wont work. This makes it a bit tricky, since you can save vs. spell against spook. Basically, its not a fair fight, since greater Malison is a very important spell, the base of all save-required follow-up spells.

So lets forget spells which require saves.
Lets talk damage [img]smile.gif[/img]
-a spell sequencer with 3 flame arrows or skulltraps deliver substantial damage. Then some Abi dalzim-horid wiltitings when required. And after that try Power word: Kill (lvl 9)
(no save, has to be below 60 hp at the time)
Another possibility is Power word : Stun (only 7th lvl), he'll have to be below 90 hp for this.

A great spell is power word : Blind (lvl 8), which blinds the opponent for a few rounds, without save.

Also, an alternative way of useing spell trigger (lvl 8)is casting it on yourself, two nice combinations are :
Defensive: Fire shield (red), fireshield (blue), mislead
try to combine this with stoneskin. Stoneskin lasts longer
in combination with mirror image.

Offensive: 3 Sunfires !! , he's gonna regret coming close to you,
when you're suddenly dealing 3 x 15d6 = 45d6 = 45 - 270 hp
damage.

P.s. Protection from magic weapons is a must
