Removing "Affects"?

[Guest Guest]

Shadowkeeper (used for quick references) has a section that notes "affects", which appear to be the permanent abilities granted by spells in-game (like the Hell trails). Although possible to add affects, I was wondering if, aside from using an editor (which isn't very useful for an in-game sequence, such as a quest), is there a way to remove affects through a scripting command? I hear tell that David Gaider's Yaga-Shura mod allow the Fire Giant's immortality to gradually wear off...although I have no first hand experience with this, the description sounds like Gaider programmed a timer that removed "affects" during the battle. Will anyone assist?

It is possible to remove timed effects prematurely by fakeeffectsexpirycheck action.

You can remove other (permanent) effects by applying a spell containing effect removal opcodes or applying counter effects.
