Problem with support magic

[Verdite]

Support magic, increasing defence, cannot be saved in my parameter editor. I click apply and save after making changes. Am i doing something wrong?

This is one of SoM's more disappointing problems. You can get the duration to save by selecting an attack spell and setting its stats, saving and then switching back to a support spell model. But, Todd noticed that the screen effects for support spells last the correct amount of time, but the actual stat boosts, fizzle out early. They only last about 1/10 the duration of the screen effects. ‎  You can still set up curative support spells, but anything with a 'duration' doesn't work well ‎

Thanks anyway, at least i know now. More holes with SoM eh.
