U41 Bug: Negative Energy Burst

[Pilgrim1]

Negative energy burst is doing about 1/4th the expected amount of healing to undead players and about 1/2 the expected amount of damage to monsters.

I do not know which aspect of this is bugged but i would guess its some combination. It is doing LESS healing then previous to U41.

please fix this ASAP - our poor PM healing needs this!

-Thanks

And now it can not be used in public areas. It sucks, fix the spell asap pls

I filed a bug report about this just after u41 was released. I also posted about it on the forums.

Another interesting bug that's crept back in is Negative Energy Burst now removes charges from spell absorb items again. It was not doing this in the recent past, although it did in various parts of the earlier game's history and was fixed then as a bug.

So between that and it not working in public areas anymore, whoever adjusted the spell did a really good job of messing it up. Please fix these problems as soon as possible.

Thanks.

This disproprtionally affects pale master builds (even though they are increasingly rare at the moment) - please fix asap!!

Hey, just bumping this 6 moths later, its still not fixed - or even acknowledged. Hear are some numbers for you to digest.

Conclusion:
Clearly the change to negative energy burst did not take, or rather some inaccurate formula was used to create it. My theory is that the current formula is 1d6/lvl. Max CL 10.


New formula
(1d6 + 4)/lvl. If it maxes out at lvl 10 it has a base of 75. If it maxes out at 20 it has a base of 150.

My toon: lvl 30 wizard in a non-arcain destiny, with master of death. CL is 20, max CL is 20. NO metamagics enabled

437 negative SP
80 negative heal amp

Formula: Base * (1+SP/100) * (1+amp/100) = expected amount.

Expected healing:
CL 10: 75*5.37*1.8=725 expected healing
CL 20: 150*5.37*1.8=1450 expected healing.

Observed: 628, 588, 628, 617, 588. Average = 610.

Expected mob damage:
CL 10: 402
CL 20: 804

Observed (factoring out crits and saves): 522, 571, 582, 594, 641. Average = 582


Changing of gear: 40 amp, 296 SP.
expected - CL 10: 416
Expected - CL 20: 832

Observed: 375, 369, 365, 331, 337. Average = 355.

When i switched to draconic i have a CL of 25 and should have a MCL of 25 as well. Using the gear: 40 amp, 296 SP i get:
observed: 348, 414, 343, 365, 375 = average 369.

This is an increase of 4% or well below the expected increase of 25% for increasing CL. Thus i assume the MCL is set at 10.

Interesting numbers. There's not a huge sample size but what's interesting to me is the fact that for the first setup the self-healing numbers are quite similar to the MOB damage numbers - this seems to indicate that negative healing amplification might be having little, if any, effect. For both runs the difference between self-heal & MOB damage numbers is about 4-5%.

If the MCL was 15 then (1d6+4)/level plus neg spellpower and no healing amp gets you pretty close to your observed numbers for you first setup. This formula breaks down for your second set of numbers though, so I suspect there's something more going on.

Given there's 3 variables here (damage dice, spellpower and neg-healing amp) running a series of samples where only one is changed (e.g. keep spellpower constant but change neg-healing amp) would help tease out the likely base formula.
