Creating new spells

Hi,

I think about creating a new combat spell who mixes two elemental effects, similar to the napalm spell. An easy example would be water and electricity damage, resulting in a knockdown test and a test for incapacitation / gear failure. My first idea was mixing acid and electricity, to create an electrically charged acid vapor but I'm not sure if that is possible. Other ideas would be fire + smoke, water+wind etc.
What if one elemental effect results in stun damage where armor is useless (like smoke) and the other effect results in physical damage resisted with half impact armor (fire). How can one combine that?

Any ideas on this?

What about an Acid Cloud (air and acid), it's an AoE attack, the greater hits can generate multiple things, coverage area, thickness of the cloud (visibility and possibly movement depending on the roll), strength of the acid, etc.

The spell design rules in Street Magic on page 158 can help you.

Having more than one elemental effect will increase the drain significantly.

From a rule perspective things are clear, regarding drain numbers etc. But from a "plausibility" perspective I'm a little lost.

Example:

"Smokey Fire" - combines smoke effect (description in street magic) and fire (crb p. 155).
indirect, elemental
Drain (F/2)+5

Scenario: Casting "Smokey Fire" on a ganger
Force 5
Assuming Caster has 3 hits, Ganger has 2, so the spell hits, Damage is 5 +1 Net hit=6.
6 Damage Smoke: Stun damage, no armor resistance (handled like an inhaled toxin)
6 Damage Fire: Physical damage, resists with impact half, followed by tests for ignition.

Does this spell really stun and physical damage at the same time? Is this the right way of combining these effects?

That sounds about right but right now I do not have access to my copy of Street Magic.

IIRC I once created physical manipulation spell that combined lightening and sound, but the drain was way too much for me to consider using with out being initiated several levels.
