This still results in nonsensical combinations of 2 spells meant to be fast but high strain into an interruptible spell with high speed and high strain. That makes no sense to me.

Pedro can you find some examples of where High Speed + 1 (High Strain +1) results in spells vastly superior to adapted spells?

John

Pedro, would you accept
Take the higher of the spells 2 speeds and add their strain together?

i think keeping the speeds as speed and strain as strain is important

I feel the same.

John

Elemental Bolt/Arc Lighting - 4 (+2) /4 (+2)
becomes 5 (+3)
Melee (1 target)
2d6 (Primary)+2

to get Arc Lighting to do the same damage you need to apply the damage boost 3 times
for CTN: +9, Strain +3 final cost of 4 (+5) and are still a few points behind on damage.

that was a quick look.

I'll be honest, the CTN's on adaptations are rather high compared to CTN for Advanced Spells. Otherwise, I don't see a big issue with that, since the Improved Arc Lightning is still a Base Spell and could be combined with something still.

John

Take the higher of the spells 2 speeds and add their strain together

turns it into a 4 (4) spell

or
Take the higher of the spells 2 speeds +1 and add their strain together?
turns it into a 5(4) spell

maybe we need to increase the CTN of the combined spell and go highest speed/strain

sure

just change CTN:
Equal to the sum of both CTNs-15.

to
Equal to the sum of both CTNs-12.

Ok... this is what we have so far

I'm ok with that, however i would really like to hear other opinions
