Weakness to "..." Spells

[The Red Robin]

I have a super spell that I use for particularly difficult enemies. I named it "Destroy More" since it is a stronger version of a previous spell I made, "Destroy." Here it is:

All effects are for one second.

100 Fire Damage
100 Frost Damage
100 Shock Damage
100 Health Damage
100% Weakness to Fire
100% Weakness to Frost
100% Weakness to Shock
100% Weakness to Magic

So my question is, at 100% spell efficiency, just how much damage does this spell do? I'm under the impression that each of the elements get a 200% boost because of both weaknesses (element, magic), and that the damage health effect gets just a 100% boost because of the weakness to magic effect. This would put the damage at 1100 points on an enemy with no resistance to elements or magic (300 + 300 + 300 + 200). Or, do the weaknesses work differently?

400 Points of Damage.., and a lot of Wasted Magicka.

Weakness to Magic increases by M% the magnitude of subsequent offensive magical effects; the effect lasts for D seconds.

Weakness does not influence any Damage effects that are included in the same spell. In other words, you must cast a Weakness spell first, then follow it up with a Damage spell to get the increased damage due to the Weakness effect.

Jeff is right. You will need to extend the time on the weaknesses so that they are still active upon the second casting (or just have them in a seperate spell).

the cheapest way is to do touch spells, make up 2 weakness to magika 100% for 5 seconds (or 3 seconds if you think you can get the spells off that quickly) give them different names, hotkey them, cast number 1 and then number 2 at target and then your damage spell (100 points for 1 second). The two weakness spells will effectively quadruple the damage of the damage spell

if you had four weakness to magika 100% spells and cast them successfully at the bad guy, followed by 100 damage spell, it would do 1600 pts damage

just make sure the enemy doesnt have reflect magic in effect
