Doublecasting NPC: Carey, Death at her fingertips Options

[bibliophile20]

Diagnose

Force 6 Stacked Focus (2 Heath Spellcasting/4 Health Sustaining)
Assorted other gear

Building her on the SR4Chargen excel sheet, she comes out to about 500 BP (465 with this, but, hey, who's counting?)

So, normal battle tactics would be to sneak in close on her target, using Improved Invis, and engage in some direct damage dealing via the following:
Unarmed 5 + Agil 5 + Touch Attack 2 = 12 melee

Assuming that she manages to touch the target, first comes a Force 4 Decrease Willpower; her base spellcasting pool is 10, so let's give the spell 5 dice... and add in 6 more for the mentor spirit bonus, the focus and the expert aspected magician quality. Rolling that against the average 3 Willpower gives her three or four hits to the target's 1, reducing him to 1 or (ouch) 0 on willpower, giving him little to no defense against the other spell being cast--a Force 6 Death Touch.

Death Touch gets the other five dice from the spellcasting pool, and then another 6 dice for the mentor spirit, the specialization in combat spells, and the Expert aspected magician. So, again, 11 dice... against, at most, 1 Willpower. If she Edges the roll, the target is toast, almost guaranteed.

Drain on both spells:
Decrease Willpower: 4
Death Touch: 2

A one trick pony? A bit. But she'd make a fun and very, very dangerous contact to have--considering the Dark Goddess' disadvantage
