Ok, so flames of devotion is also bugged. The (tested) formula is:

• w/o intense flames: 0.5*rolled dmg - 0.25*fireDR 
• w intense flames (another +25 burn dmg): 0.75 * rolled dmg - 0.5* fireDR

 

Even the formulas themselves are wrong because the base flames of devotion does not take into account 0.5 of the fire DR but only 0.25 of the fire DR. This makes no sense whatsoever. The intense flames adds another 0.25 dmg and another 0.25 fire DR but to the wrong base.

 

However, even the above formulas don't work 100% of time. I found few occasions where the result is not the expected one:

 

 

Pallegina has intense flames talent and Eder has 14 fire DR. Applying the formula from above we should have an extra fire dmg of: 11*0.75 - 14*0.5=1.25. Which is not what happens in the game.

 

A supposition: even if we consider that fire dmg from the ability is also subject to the minimal of 20% dmg rule, which I don't think is the case, we should have: (11*0.75)*0.2=1.65. 

 

As you can see from the picture above, I've made quite a few tests with both Pallegina and Asda. All the other calculations followed the formulas that I've mentioned above but this one. 

 

later edit: I've made some more tests and again I found one occasion when wrong calculation happened. I believe that it happens only with very low rolled dmg (min dmg with standard attack) and it might be that intenese flames have something to do with it as well since Asda paladin (which doesn't have intense flames) did not react like this no matter how low the rolled dmg was.

The insane dmg dealt to higher lvl slimes/oozes (swamp slime, greater black ooze, disease pudding etc) is not fixed as of patch 1.05. I posted already an example in post #4 of this thread (it's from patch 1.03 but it's still valid). I think it's high time someone looks at the damage calculation for these creatures because it's massively bugged. I've stopped  exploring endless paths at lvl 4 because of this.
