Do Health Degen's stack?

This is something I have wondered for awhile. Placing multiple hexs/spells on a target where each causes a health degeneration of some kind.

Example: Conjure Phantasm and Crippling anguish. Assuming you had a lvl 12 in illusion you would be causing a degen of 5 and 3. So what I am asking is whether the health degen is actually 8 or whether it simply takes the higher value of hex, in this case 5.

This is confusing especially with multiple ways to add more degen, like apply poison and other players phantasms.

Someone inform please.

[COLOR=DarkGreen]im pretty sure they do
atleast i had multiple DoT's going on at once, and every sec over the persons health it would say -5 - 2, although i think there may be a maximum amount of health degen someone can hve.

although im not sure on this number, or if there even is a numer...?
but im pretty sure youll be dealing -8 a sec.[/COLOR]

Also, for health degens, if you didnt already know, you lose double the number of degen pips you have. So if you had a 5 pip health degen, you would be losing 10 health a second.

You can stack as many health degen as you like also, as long as it isnt the same skill, so two conjure phanstasms cast by the same person wont net you -10 degen, it would just reset the timer on when the previous one ran out. I am pretty sure that they would stack though if two different people cast the same Hex on someone. (I.E. Player 1 casts Conjure Phantasm on Player A, then Player 2 also casts the same spell on Player A. Player A should have -10 degen if I am not mistaken.) Correct me Alphas if I am wrong .

ah, I thought it had changed. Guess you don't notice everything though when you only have a weekend to play .

thank you for your helpful replies

On that note, I have noticed some skills say "slowly loses health over time." The vagueness can lead to alot of assumptions. Is it just that we don't know or aren't meant to know?

It's more that the game's still in development and they haven't gotten around to standardizing their skill descriptions to the level that they should be in release. Things are missing or misleading in many skill descriptions but when they change as rapidly as they do, that's expected, as things get closer to release some poor staffer at ANet will probably be relegated to the role of going through all the skill descriptions and making them as clear and precise as possible. At least I hope so because I can't even make heads or tails of things sometimes...
