  • 0. Glyph of IBF, with more testing!   04/19/2009 11:13:10 PM PDT

I know there's already a separate thread on this, but I felt that I had enough test data on my own.

TL; DR: The Glyph of IBF, as of April 20, 2009, 1:58 PM PHT, simply increases the baseline DR of IBF from 20% to 30%. It will still scale with defense, to the tune of 50% DR at 540 defense.

This test was performed using the lava in the Maw of Neltharion, with no talents to decrease spell damage, except that which was completely under my control.

Test #1:

No IBF Glyph, 400 Defense, Blood Presence, No IBF: 602 damage ticks.
This forms our baseline.

Test #2:

No IBF Glyph, 400 Defense, Frost Presence, No IBF: 571 damage ticks.
This is just to confirm that the lava is reacting correctly to damage reduction effects. We received a 5% reduction here, as expected.

Test #3:

No IBF Glyph, 400 Defense, Blood Presence, with IBF: 483 damage ticks.
This is just to confirm that unglyphed IBF is working correctly. We received a 20% reduction here, as expected.

Test #4:

No IBF Glyph, 541 Defense, Blood Presence, with IBF: 355 damage ticks.
This is to confirm that unglyphed IBF is scaling with defense. We received a 40% reduction here, which is consistent with 0.14% extra DR per point of defense skill over 400.

Test #5:

No IBF Glyph, 507 Defense, Blood Presence, with IBF: 385 damage ticks
This is to confirm the scaling factor on unglyphed IBF. We received a 35% reduction here, which is consistent with the expected 15% extra DR from 107 defense over 400.

Test #6

With IBF Glyph, 400 Defense, Blood Presence, with IBF: 421 damage ticks
This is to confirm that the Glyph of IBF does increase the non-defense DR from 20% to 30%. We received a 30% reduction here, as expected.

Test #7

With IBF Glyph, 541 Defense, Blood Presence, with IBF: 295 damage ticks
This confirms the bolded text above. Defense scaling from 141 defense skill over 400 would add 20% DR. Add that to the established non-defense, Glyphed DR of 30% and you get an expected 50% DR. We received a 50% reduction here.

Test #8:

With IBF Glyph, 507 Defense, Blood Presence, with IBF: 325 damage ticks
Similar to test #5, this confirms the scaling factor. 107 Defense skill over 400 would add 15% DR. Add to that the established non-defense, Glyphed DR of 30% and you get an expected 45% DR. We received a 45% DR here.

Do you have a WWS to link also? There will be naysayers and this would shut them up

Unfortunately, I never learned how to use WWS or /combatlog. I can redo the tests and take screenshots, if anyone doubts me.

So what exactly is the formula for Defense to bonus IBF reduction?

The new inscription books are as ridiculous as having to farm for rare drops before you're allowed to spend talent points.

Glyphs are not gear, don't treat them as such.

There were multiple posts from people I didn't acknowledge throughout the ptr testing process stating this same thing. I never once saw a WWS or screenshot to support any of it, so I never bothered giving it any thought. Plus, I like glyph of rune strike.

Hopefully if this is ever changed because they don't like 50% mitigation on DK's in pve, they'll let us know.

1 def over 400 = +.14 mitigation, as prinsesa stated.

So at 898 defense, IBF will reduce damage taken by 100%

What's the max obtainable with current gear?

Something in the neighborhood of 1286 defense rating, or 261 additional defense skill, or 661 final defense skill.

And this is assuming something ridiculous such as JC/BS, triple Thick Dragon's Eyes, ignoring all socket bonuses in favor of mass Thick Autumn's Glow and the TBC-era Vindicator's Armor Kit on your gloves and pants.

With a Glyphed IBF, that's 66.6% DR.

I really hope this is a bug, or this glyph is going to become mandatory. :(

Thanks for testing this!

So after i saw this i was curious which woudl be better to use. IBF glyph, or UA.

I made a quick spreadsheet and i was quite surprised at what i found about UA.


It sucks...

The new IBF glyph (+10%) reduciton, will provide (on average) for a frost DK:
3% Damage reduction (without set bonus)
3.5% Damage reduction (with set bonus)

Now comparing the UA damage reduction is hard, becuase it is variable (based on the damage coming in). However to give a few key numbers here is the extra mitigation provided by UA at different damage levels

(assuming 30,000 armor)
2,000 =2.5%
2,500 = 2%
5,000 = 1%
75,00 = 0.7%
10,000 = 0.5%
12,500 =0.4%
15,000 = 0.3%


This is the additional damage reduction provided by the Glyph.

As you can see, there is essentially NO reason for you to take the glyph, unless you are being hit by thins that do around 2-3k damage after mitigation, which really isnt life threatening. So unless your doing adds on Sarth 3d etc.. it really is not worth taking.

I just don't see this being worth a glyph slot. The only time I ever died all week during IBF up. is on Mimiron trying to use it to go through a barrage.

You used IBF on an ability you were supposed to avoid, which was guaranteed to kill you? Wonderful.

IBF has a 1 minute CD with a 21 second uptime with 4pc. The new Glyph is the icing on the cake and makes it that much more better.

It is pointless. You don't die with ibf up. You haven't even done Ulduar past like flame leviathan you don't have a clue what you are talking about. The tank being able to cooldown the blast would mean he wouldn't have to try and turn the boss risking killing the raid.

What the Shaman said was right. Fact of the matter is IBF now with a guaranteed INCREASE of 10% damage reduction making it a minimum of 50% reduction at 540 defense is a godsend. Especially when you run with 4pc as frost.

Try again.

Again you are just wasting your glyph spot on something that won't save your life.

Old ibf glyph could have atleast saved your life if you needed it when you were out of rp.

*Sigh*

Not every cooldown is used as an OH!%!#IMAGONNADIE button. 50% guaranteed damage reduction for 21 seconds every minute reduces healer stress.
