My idea is that a blocked spell has lower magnitude and duration, and increased area of effect. I actually made a working mod for this, and I'll send you the files if you want to test it out.

I was wondering if any of you have ideas about spell blocking, and if you'd share them. Maybe I can implement some of these ideas.

This looks neat... I've always wanted to be able to hunker down behind my shield to disperse a fireball... I even remember in Morrowind, you could sort of counterspell enemy casters by lobbing another spell at theirs... the two spells would meet in midair and go off right there. That was really cool, kinda like blocking the spells. Why can't we do THAT in Oblivion? *pouts*

I remember seeing a mod that does that on YouTube long ago.

Which did you see? Blocking spells or shooting projectiles that are in mid-air?

Bouncing fireballs right back to the caster by using shield. Or somewhere aside if you aren't skilled enough.

Don't let the fact stop you though, always good to have variety

Oh! I haven't seen that you're working on that too! Cool! Good luck!

I tried to look for that video, but no success.

It could have been omzy's spell deflection mod. Basically you can deflect the spell back at his caster if your block skill is high enough, or you can decide to shoot somebody else. When you're not good enough, you either don't block it or the spell goes in the ceiling, floor, etc. Quite a neat mod that has never left my load order since I tested it.

edit: I remember that in morrowind you could also block incoming spells with arrows

It would have been a much more "magic-savvy" idea to enable counteracting enemy spells with those of opposite effects. I.e., to "block" a fire-based spell with a frost-based one.
