I'm not much of a mage player. My Cultist is my recent character that uses destruction magic and the like but I heard something interesting. Let me get this straight. If I cast 100% weakness to Magicka 100% weakness to Fire Magicka (for example) in one spell and it lasts 10 seconds, then I hit an enemy with it again it stacks? I always assumed it'd simply reset the duration.

Say you have a spell:

Weakness to Fire 100% for 10 seconds on Touch
Cast this spell, then within ten seconds, cast your fire damage spell, and do double damage.

Here's an interesting scenario:

Say you have a spell:

Weakness to Fire 100% for 10 seconds on Touch, and you named it, "Fire Prep 1."
Say you have the exact same spell, with a different name, "Fire Prep 2."

Cast Fire Prep 1
Cast Fire Prep 2
Cast Fire Damage Spell
Do quadruple damage.

Marvel at one-hit kills that doth flow from your fingertips. Well, not exactly one-hit, as you are using two prep spells, but... you get the idea. Touch is faster, and almost a guaranteed hit, than target. Also costs less, magicka and money-wise.

EDIT: And yes, put the Weakness to Magic on the end of each prep spell. Might want to add soul trap to the damage spell (depending on how killer the spell is) seeing as to how much damage you are dealing.

My favourite is to add a short term weakness after the damage, fire damage 25 + weakness to fire 100% for 3 seconds. if you can cast weakness to magic put weakness to magic 100% for 3 seconds behind weakness to fire, this would cause each hit to do double damage.

Yes it's more expensive than a special weakness spell but far simpler to use in the heat of battle. Downside is that you has to continue hitting the enemy before the spells times out.

Long term weakness to fire work nice together with a summoned fire elemental, very nice against dangerous enemies with reflection like liches.

It does reset the duration in all cases. However Weakness to Magic is interesting because Weakness to Magic is itself Magic.

So to take a simpler case. If you have a Weakness to Magic 100% for 10 sec then cast it twice within 10 seconds, then the second will replace the first, but the first will also magnify the second cast for a total of 200% weakness to magic. If you cast it a third time the second will magnify the third to 300%. And so on.

This isn't exactly spell stacking because the next cast replaces the previous, but it's close.




No. It will cause triple damage, not quadruple.

Thanks for coming to do the math for me! :spotted owl: I've never paid attention to the actual numbers when figuring out how magicka stacks. I've just paid attention to how fast my enemies keel over with combinations of these kinds of prep spells.

If you made the same two spells with Weakness to Magic, instead of Fire. You'd get quadruple damage.

Your need 100% amplification from the first spell and 200% from the second. For a total of 300% amplification.

So in that case a 100 point fire ball will do 100 + 3x100 = 400 points of damage.

So you add the weakness to magic effect not multiplying it. Weakness to magic 100%, 200%, 300%, 400% not 100, 200, 400, 800?
Makes my test results to make far more sense, it will also multiple an elemental weakness.

As I understand a spell with fire damage 30, weakness to fire 100% for 3 sec and weakness to magic 100% for 3 sec will do
30 in damage on first hit,
30*(100% elemental+100% magical)=30*2=60 hp , accumulated 90
30*(200% elemental+200% magic)=30*4=120 hp, accumulated 270
30*(3* elemental + 3 * magical)=30*6=180 hp, accumulated 450
It seems to fit pretty well with my experience.

Yes. That looks right to me.

The thing about Weakness to Magic that makes it special is that it increases all magical effects, even another Weakness to Magic cast.

Note that to get the above results, Weakness to Magic has to come after Weakness to Fire in the spell you mention. If it came before the Weakness to Magic in the second cast would be amplified but also replace the first Weakness to Magic before it affects Weakness to Fire in the second cast. Sorry if that sounds confusing. But if the order in your spell were revised with Weakness to Magic then Weakness to Fire, on the second cast you'd get 200% Weakness to Magic but only 100% Weakness to Fire (because the first cast's weakness to magic was replaced before hitting the second cast's weakness to fire).

Thank you everyone! I made a 10 damage spell destroy a storm atronach in one hit
