The first thing I'm looking to set up is a set of "combo" spells. I want the player to use a concentration spell on a target. If that target is an NPC Actor that is dead, I want it to apply a visual effect to him. (Something like the SoulTrap effect, but lighter.) As the player continues to channel at the target, I want the glow to become brighter and brighter. After a certain point, I want it to cap out. If the player stops channeling the spell on the target for any amount of time at all, the effect should fade completely.
The second part of the combo, would be a long channeling spell with a dark effect. Kind of like the bound weapon spells but not quite. If there's a "unique" 1h spell casting animation for powerful spells I'd like to play that too, but I don't know if there is one. Once he fully "builds up" the spell and releases it, it should run a script on the target. This script should only succeed if the target is at the "cap stage" of the concentration spell.
Now, I have a general idea of how to do most of that. I can make a really long cast time for the second spell, give it effects through the effect window, and run a script using "OnMagicEffectStart". The part that I really don't think I'd be able to do, is the "accumulating spell effect" from the concentration spell. I'm also not too sure how scripts work on concentrated spells. Will the script run several times per second because it's concentration? Or will the script only run once every time it finds a new target?
Any help is appreciated, thanks.
