KB Resistance for Dark Armor

This is a totally newb question.....
but I have been playing the game nearly 4 years now and I have TOTALLY forgotten which set of IOs offer that KB resistance that helps out the Dark Armor powers
If memory serves the IO goes to lev 30....
but I cannot remember the name of it
Seems like there were two different sets of IOs but I could be wrong
Forgive my Uber-Brain-Farting power that I have (it's fully slotted by the way)

Steadfast Protection is the set with the KB protection.

Blessing of the Zephyr
Karma

There are three KB Protection IOs: Karma for Defense powers, Steadfast Protection for Resistance powers and Blessing of the Zephyr for movement powers (not including Sprint, prestige sprints, Swift, Hurdle, Lightning Reflexed, Quickness or the like).

You can also get KB Protection from 4-slotting Kinetic Crash (Knockback) or 5-slotting Gladiator's Javelin (Ranged) or 3-slotting Fury of the Gladiator (PBAoE) or Gladiator's Armor (Resistance).

Danke mucho everyone
I have used one or two of them in the past but for the life of me I just couldn't remember the names.
In the past I would just browse the crafted IOs at WW and select the info tab by right clicking on it for the knowledge of each IO and for some reason recently searching thru IOs like that doesn't work anymore.
Oh well.
Grassy-*** once again

The multi-slots (Kin Crash for instance) are only mag 3 instead of mag 4. I remember slotting that once and getting somewhat more KB'd than with the 4 (which stops an estimated 90% of KB. You can still get hit by synchonized grenades or individual nemstaff shots or whatever, but MOST kb just goes away.)

There's also, in the short term, this, but it only lasts an hour before refresh. It'll get you through a couple missions before you have to run back to the SG base, though.

Depending on what you're playing, you may want multiple -KB bonuses in play, also. For example, I usually have only one on Scrappers or Stalkers.

I'll usually go with two on Brutes (for a total of either 7 or 8 points depending on if I use Kinetic Crash or a -KB IO).

On my Fire and Dark Tanks, however, I like to have 11-12 points to make myself pretty much immune.

If you find yourself not wanting to use multiple slots on the KB protection, you could go a different route with i19's inherent Fitness, freeing up some power choices so you can snag Leaping pool powers and Acrobatics for its Mag-9 protection. (Can add some Defense IO's to Combat Jumping too...). Just a thought.
