Cap on stacks of Degenerative -Max HP?

Was wondering if anyone had tested out if there's any cap as to how many times the -Max HP proc could be stacked on an enemy. City of Data doesn't mention any form of cap on the -Max HP portion but in solo testing I've found that my pets and I are able to keep the proc stacked 4 times on an enemy. As I was testing on Pylons,Monsters,AVs, each proc hit for about -1000 max hp bringing me up to a consistent -4000 max HP at max stack.

Does anyone know if this 4max is per player or per NPC? Would 8 of me be able to maintain a -32000 Max Hp on pylons,monsters,AVs? I know that may sound a bit ridiculous, especially in leagues, but I only ask because I wasn't active when these were released and looking through older threads I get the impression that this is possible.

4 stacks per NPC limit, same as all other interface debuffs. Interface DoTs have a 8 stack per NPC limit.

Note that it's 4 stacks per debuff, and that each debuff has different strengths depending on exactly which ability you have slotted.

I don't know the numbers for Degenerative, but let's say the different strengths are 500, 750 and 1000. Each power in the Degenerative tree will have one of these values. Any powers with the same value apply the same debuff.

So, in this case, if you had at least one person with each strength, you could stack 500x4, 750x4 and 1000x4. But you can never stack more than four of each at a time.

I *think* it's -150 hp per, but not certain.

It provides a temp power tp the target that only allows it to stack so many times. Thus no matter how many people have the interface debuff, it will never go over 4 unless as previously mentioned above (different numbers, but the cap stack is the same per number).

Thanks, folks. Was aware of the standard 4 proc stack max, but since -Max HP is kind of a new thing I wasn't sure if it was being treated any differently.

The -HP interface ends up to -150hp on AVs and GMs. Just an heads up.

Here's some screens from a pylon fight and a 54 Diabolique EB (forgot to bump up my difficulty to make an AV).

As you can see on the pylon, the -HP is pretty consistent of about 1000 per proc, roughly around 3-3.3% per proc. I'm not sure why the numbers vary if however. Well, maybe when the next proc fires it calculates off the current lowered max HP. Not sure.

Kinda more of the same here, but the proc values seem to be much more varied. If it's supposed to be a set percentage than the variance in the values here doesn't make a whole lot of sense. Only other thing I could think of is that the normal of the value of the proc is 45-60 for this NPC and it's being applied 6 times here... or it's just not displaying correctly.

I have seen combat numbers show a stack of procs from the same player just double the value on a single line as shown in this pylon screenshot... http://i.imgur.com/hWLE7.jpg ... the first spiderling is applying the proc twice while the second only landed it once. Still, we're hitting at about 4 procs total here. Using the logic on this screen, it almost does in fact seem like the proc is landing roughly 6 times on the Diabolique fight, despite what we're being led to believe about the 4 stack max.

Would really be interested in putting together a team of 'Degenerates' and doing some further testing on this.
