This is my tweaked version of Oblivionmasta's IHI. Actually, 'tweaked' is the wrong word. I built the script from scratch. If you've used Immersive Health Indication before, you'll know what this does. However, it wouldn't be Immersive Health Indication+ without some added features:

 - More intensity options; keep in mind that this mod uses a faster update than Immersive Health Indication, so lower values are here.
 - More threshold options
 - Linear/Quadratic blur: IHI had the quadratic only, this lets you decide if you want it blurred at early damage levels or not
 - Threshold/HP based: Should blur be minimal when threshold is reached or only HP-based?
 - Throb blur: The blur will throb with your choice of percent and frequency (don't worry this is totally optional)
 - Customization mode? What's that? I just made it to where you can change the options through the console no matter which ones you pick.

To customize, open the console with '~' and type "set XXX to YYY" where X is the variable and Y is the value you want.

set IHI to (0-5)
- Just use 0 to go through the options again
set IHImag to (0-10)
- Sets the strength of blurring. I recommend not using a value higher than 10.
set IHIpercent to (1-100)
- Sets the percent to start blurring. Setting this to 0 or lower will restart the mod.
set IHIquad to (0-11)
- XY; set X to whether it should be quadratic and set Y to 1 to use max HP instead of threshold percent
set IHIthrobpercent to (0-200)
- Blur will "throb" by this percentage
set IHIthrobtime to (0-10)
- The number of seconds between "throbs"; setting this to 0 will not crash, but disable this feature, you cheeky butt.

Probably doesn't require OBSE...probably.

Well, that's about it. I'll give a shout-out to Oblivionmasta since his mod gave me the idea. You can find it here: http://www.nexusmods.com/oblivion/mods/3910/
