Do Sk and Necro spells stack or does the higher one (obviously the Necro) win out? On say a darkness DoT?
In most cases they stack. Higher darkness spell got a seperate snare / dot component. The snare will be overwritten while the dot part will stick. Perhaps if they both are using stats debuff disease dot there would be an issue on the debuff :slot but that's it.
Some spells like the heart flutter line may not stack, if the necro has a higher level version than the sk. Or even 2 sks if the higher level sk version is used it will over write the lower level one.
Eventually SKs get their own line of spells so there is no competition except for things with other components like snare.
