Guild Wars 2

scenario : a support class character A with certain amount healing power stats and +boon duration stats. A casted skills that give regen and few other boons, and a few allies nearby are affected.

question 1 : does the effective healing from regen received by the allies around A depend on the healing power of A, OR depends on the individual healing power of each of the allies ?

question 2 : does the effective boon duration received the allies around A depend on the +boon duration of A, OR depends on the +boon duration of each of the allies ?

@Saturn
Poison (and Agony) reduce INCOMING heal. If A heals B, the recovered HP depends on B being poisoned and ignored A being poisoned.

Affected by source:

• Boon duration
• Condition duration (+x%)
• Boon power (healing for regeneration; power for retaliation)
• Condition power (condition damage; various traits/ sigils/ runes)
• Damage power (power; +x%)

Affected by receiver:

• Condition duration (-x%)
• Heal reduction (-x%) (Poison/ Agony)
• Damage power (defense; -x%)

Basically saying, all effects which makes it stronger, depend on the source, all which makes them weaker, depend on the target.

Answer1:
The healing from Regen is affected by the HealPower of A.
Proof: If A has Poison, it makes no difference on the healing that B gets. If B has Poison, B gets 33% less heals from A.
(Therefore B’s HealPow never comes into play unless B heals).

Answer2:
The boon duration applied to B(by A) is dependent on A’s BoonDur (same as above, B’s BoonDur never comes into play unless B boons up).

Pretty much like this, just want to add:

• Agony reduces incoming healing by 50% (Poison only 33%)
• Whoever distributes boons/ conditions “controls” its properties (strength & duration); remember that the reciever can lower his incoming condition duration by some means.
• If multiple instances of the same boon (except might) are applied by different sources, the strongest source will be used first, regardless of the order or duration.

Turtle Dragon.9241:

This would actually imply that B’s healing power is used.

Turtle Dragon.9241:

(Therefore B’s HealPow never comes into play unless B heals).

B heals less if B is poisoned. Again; obviously B’s healing power is reduced and not A’s, thus A’s healing power doesn’t have any effect.

I might add that it’s still possible that it IS affected by A’s healing power… but I think poison might be the wrong example. As far as I understand it, poison doesn’t reduce healing power, but the amount your heals heal… what I mean is, the number gets calculated normally and then (if the person that’s to be healed) has poison, 33% are subtracted.
The easiest way to actually test it would be to have two characters with a different healing power applying renegeration to eachother (obviously not at the same time).

I think I’ll have to test that at some point, because I always thought it’s different. And after your contradictory example above, I don’t really feel like just believing you. ^^

boon duration and healing effectiveness depends on the source (player casting it)
if receiving player have poison, then ally will get healed for 33% less (poison condition on casting player have no effect on this)

e.g. if i have FGJ shout that has 47s might duration(depends on my boon+might duration, in this case +85%) and heals for 1200hp (depends on my healing power), then i and up to 4 nearby allies will get 47s might duration and will be healed for 1200 (800 if receiving player got poison) – therefor receivers’ boon durations and healing powers are irrelevant

Hm, okay. I’ll believe you that then. Meh; too bad swiftness duration from runes doesn’t affect the swiftness I get from other people (and neither does my boon duration). Oh well. ^^
