I5 Compiled Invulnerability Numbers
by Lightning Bug (Issue 5)

This is all info I pulled from various sources on the official site, and confirmed with Triumph over the last several days. I thought I'd post it here so you guys didn't have to surf through 42 different threads to compile it all. I added the rounded percentage increase for each power you get by adding one SO (sorry, I don't have the numbers for Training or DO enhancements) so you can do the math in your head to figure out about where your tanker will be come Issue 5.

Resist Physical Damage
Base - 7.5% smashing/lethal resist
per SO - 1.5%

Temporary Invulnerability
Base - 30% smashing/lethal resist
per SO - 6%

Resist Elements
Base - 7.5% fire/cold/toxic resist
per SO - 1.5%

Unyielding
Base - 5% smashing/lethal resist
Base - 10% fire/cold/toxic/energy/negative energy resist
per SO - 1% smashing/lethal
per SO - 2% fire/cold/toxic/energy/negative energy
-5% Defense debuff

Resist Energies
Base - 7.5% energy/negative energy resist
per SO - 1.5%

Invincibility
Base - 3.5% Defense per melee foe (all but Psionic)
Base - 1.75% Defense per ranged foe (all but Psionic)
(above numbers are cumulative up to a maximum of 14 foes)
No inherent Defense
per SO - 0.75% melee
per SO - 0.35% range
(I don't have the ToHit Buff numbers, but I found it almost mandatory to 6-slot it with Defense Buffs anyway, and add an accuracy enhancer to my attacks. Your milage may vary)

Tough Hide
Base - 5% Defense (all but Psionic)
per SO - 1%

Unstoppable
Base - 70% resistance to all damage types but Psionic
per SO - 14%

I found that using Havok's spreadsheet and just plugging in the post-I5 numbers where appropriate was a big help in planning how to respec Triumph. It can be found at:

Havok's Ultimate Spreadsheets of DOOOOOOOOMMM!!!

And for those wondering, the maximum resistances an Invulnerability Tanker can have at level 50 are as follows:

98% Smashing/Lethal
40% Cold/Fire/Toxic
40% Energy/Negative Energy

Hope you guys find this info useful. Let me know if anything needs correcting or added to.
