Converting Spells, SR? to SR4 Options

[BookWyrm]

OK, with the errata for Street Magic in the works, I recalled some spells that I had written up (back in the day when I & several others did an APAzine called Scrawls from the Sprawls) and now, with SR4, thought they could use some updating. Since I'm not quite yet familiar with the new system yet, I thought I'd post them here, get your feedback & see where it goes.

This is how they were orignally printed (again, many thanks to Stephen Kenson who helped flesh them out at that time). I've also included the Design Notes as well;

SHOCKWAVE (Combat)
Type: Physical Range: LOS Duration: Instant Drain: M3
Description: This spell forms a sort of invisible magical 'grenade' that detonates at the designated target & sends out a blast-wave of force. The spell does Stun damage with a base Staging of 2 & a Force equal to the caster's Sorcery skill. The blast is treated like that of a normal grenade, losing 1 point of Force per meter from the target. Impace Armor does protect from the secondary blast-wave, but the 'ground zero' target of the spell gains no armor bonuses. Magicians sometimes use this spell against floors to create a powerful blast to stun or knock down opponents. If the spell is used in this manner, have all targets in the blast radius make a Quickness Test against the caster's Sorcery; -1 to Tagert # per meter from the center of the blast.
Design Notes: Staging 2 Combat Spell (M1), Drastic Effects (+1 Category, +1 Staging), Stun Damage Only (-1 Category), Physical (+1 Staging).
Several styles emerge from this one particular foumula. It can be a wave of force & blow outward, or it could only cause shocks along a flat surfacelike the groung or a floor. If the spell is only made to knock targets down & not cause damage, it becomes a Manipulation spell.

I'll post the other spells later.
