[LE] Reflect spell damage or spell

[TairaNoritsune]

Task 1. Want to create an enchantment, that would reflect [%] of spell damage of certain type (lightning for example) back to caster.

Task 2. Want to create enchantment, that would reflect certain spell type (fear for example) entirely at caster

 

However, I am struggling at understanding, how spells in Skyrim work. reading theory on creationkit com website and attempts to reverse-engineer that spell reflection ward and spellbreaker mod yielded me nought, so I come here for assistance.

 

First of all, could this be done without scripting at all? Secondly, is magic effect with [Reflect Damage] or [Reflect Arrows] as [Associated item 1] applicable to achieve this. If yes, then I do not understand how exactly can I make them differentiate the exact damage type (lightning for example).

Reflect Damage is tricky. I have messed with it myself and have a spell that kinda works for it, but even if I set the effect magnitude at 100, it still doesnt appear to be reflecting the full damage to the attacker, only part of it.

 

I was messing around with Colorful Magic, which has tons of interesting magics, even a reflect damage spell, you should check it.

Havent had the time to properly investigate everything about it since mine kinda works as I want for now.

The Colorful Magic one, for some reason, uses the same reflect damage effect 3 times, I have no idea why. Maybe each one reflecs 33%?

 

Dunno. Anyway, I think Reflect Damage only works on melee attacks, but not entirely sure.

 

I can tell you about another thing that works though, which is a script with an OnHit event

Setting the conditions for the hit to apply, can be messy, but it seems to work.

Mechanic is simple, wearer of the effect gets hit, event happens, you can make something happen after that to the attacker registered on the hit event.

My experiment on it is simpler though, it only casts a spell. But you want it to return damage, so you might be better off with functions to register how much damage was done, and re-apply it to the attacker with a simple DamageAV("Health") function

Well, will try to look at examples and reverse-engineer them.

 

But meanwhile, could anyone explain to me, how exactly "Magical Effect" category works. I have read the description of parameters on construction kit website, what I would like to know is, how exactly they could be used. If anyone could give me examples with description what is set up in that particular way and why, I would be greatful.

I cannot explain how does "Magical Effect" category works. But maybe next could be a step in the right direction. This is not for enchanted armor, its a cloak ability for actors.
