I noticed this problem towards the end of Domination when my Summoner, who has 10 mana regen more than was needed to sustain a level 20 Arctic Armour with buff effect was losing approximately 3 mana/second while running Arctic Armour. I added the standing cost of Arctic Armour with the moving cost of Arctic Armour, multiplied it by my buff effect %, and no matter what number I came up with, it should have been enough to sustain Arctic Armour, but it just wouldn’t.



I have now came across the exact same situation when trying to sustain Righteous Fire on a low-life Solaris Lorica build. So I’m going to provide the numbers, and all available information I can in hopes that someone here can either confirm that I’m right, or tell me why I’m wrong.



I’ve came across two situations, one where I have 20.9 more Energy Shield regen than needed to sustain Righteous Fire, and it works, and a second situation where I have 10.8 more Energy Shield regen than needed, and I cannot sustain Righteous Fire.



Note: For anyone wondering why I have the 6% buff effect, and not Inner Force’s 15% buff effect, it’s because it combined with the aura effect nodes around the North half of the tree allows a level 20 Purity of Fire to give 7% Max Fire Resist, whereas without the 6% buff effect, it only provides 6% Max Fire Resist. This overall makes sustaining Righteous Fire easier, as the 6% increased damage taken from Righteous Fire isn’t nearly as much as an extra 1% Max Fire Resist protects from.



Situation One

Fire Resistance: 92%

Buff Effect: 6%

Life: 713

Energy Shield: 4552

Energy Shield Regen: 329.2



RF Cost: (92% Fire Resist)*(6% increased buff effect)*[(90%)*(life)+(70%)*(ES)]

= (0.08)*(1.06)*(713*0.9 + 4552 * 0.7)

= (0.08)(1.06)(3635.59)

= 308.3 Fire Damage/second



Situation Two

Fire Resistance: 92%

Buff Effect: 6%

Life: 861

Energy Shield: 4595

Energy Shield Regen: 332.3



RF Cost: (92% Fire Resist)*(6% increased buff effect)*[(90%)*(life)+(70%)*(ES)]

= (0.08)*(1.06)*(861*0.9 + 4595 * 0.7)

= (0.08)(1.06)(3758.93)

= 318.8 Fire Damage/second





So as far as I can tell, both Situation One, and Situation Two should be able to sustain Righteous Fire, but only Situation One works in practice. My first assumption was that the buff effect applied first, and then rounded up, in which case the math would be:



roundedUp[90%*106%]*life + roundedUp[70%*106%]*ES

= roundedUp[95.4%]*life + roundedUp[74.2%]*ES

= 96%*life + 75%*ES

= 96%*861 + 75%*4595

= 4134.96

= 330.8 after Fire Resist



However as you can see, I should still have just barely enough ES regen to sustain Righteous Fire using Situation Two, but it still drains approximately 3-4ES per second(that’s just a guess, since I don’t have any way to actually tell.)



Did I do something wrong, am I forgetting something, is the Character page really wrong?



Thanks for any help any of you can provide.



TLDR: Is my math wrong?
