After seeing complaints regarding a "Stealth Buff" to damage, I decided to do some testing.
Method Take 10 hits of damage in full gear and 1 hit of damage naked. This was repeated for the following effects. Tested in Breeched Keep level 2.
- Soul Lasher Attack
- Frozen
- Molten
- Plague
- Desecrator
- Arcane Sentry
- Wall of Fire
Armor and Resistances In Gear
- Armor: 7105 (69.02% reduction against mLvl63)
- All Resist: 802 (71.85% reduction against mLvl63)
- No reduction against Melee/Ranged Attacks
Armor and Resistances Naked
- Armor: 292 (8.48% reduction against mLvl63)
- All Resist: 7 (2.17% reduction against mLvl63)
- No reduction against Melee/Ranged Attacks
Soul Lasher Attack
- Naked: 68092
- Gear: 6600
- Reduction: 90%
Frozen
- Naked: 62443
- Gear: 6000
- Reduction: 90%
Molten
- Naked: 5986
- Gear: 2100
- Reduction: 65%
Plague
- Naked: 5702
- Gear: 1700
- Reduction: 70%
Desecrator
- Naked: 12643
- Gear: 4200
- Reduction: 67%
Arcane Sentry
- Naked: 68035
- Gear: 6600
- Reduction: 90%
Wall of Fire
- Naked: 13362
- Gear: 13359
- Reduction: 0%
Analysis
- Additional damage reduction from armor alone is 66.4%
- Additional damage reduction from resistances alone is 71.22%
- Additional damage reduction from both armor and resistances is 90.32%
Soul Lasher, Frozen, and Arcane Sentry Damage was in line with expected damage reduction.
Molten, Desecrator, and Plague Damage only appears to be affected by one source of damage reduction. Experimental values are closer to the expected reduction of only armor, however the expected reduction of only resistances is within the experimental error.
Wall of Fire does not appear to be affected by any sort of damage reduction.
