Talk:Effect stacking

Should there be links on this page to these two Anet generated articles that give numbers for different stacking effects? Running the Numbers and More Mechanics and Stacking

I found these linked on the old wiki's Stack page, but since the articles themselves are not generated from the old wiki, I assume it would be fine to put them here.BladeDVD 16:48, 15 November 2008 (UTC)
 * I went ahead and added blocking to the table. I did not compare info in the rest of the linked articles to what is already on the page for completeness or accuracy.BladeDVD 16:55, 15 November 2008 (UTC)

Activation time increase cap
In the summary for this edit, Monte Mac Manannan states the following: "changed activation modification cap from 50% to 150% [test:: (Migraine 100% + Arcane Conundrum 100%) causes the same casting times as (Migraine 100% + Frustration 50%)]" The test methodology may be flawed. For example, if the cap is 50% or 100%, Migraine + Arcane Conundrum and Migraine + Frustration would both result in the same casting time. In order to verify the cap is 150%, the skill activations would need to be timed or compared to a single 100% effect. -- Gordon Ecker (talk) 01:49, 27 November 2008 (UTC)
 * He's correct, I just confirmed it in Augury Rock, Meteor Shower takes 12~13 seconds to cast while hexed with Arcane Conundrum and Migraine. -- [[Image:User Gordon Ecker sig.png]] Gordon Ecker (talk) 02:42, 27 November 2008 (UTC)

None
IMO we should replace all instances of "none" in the table, as it is not clear whether it refers to "no stacking" or "uncapped stacking". -- Gordon Ecker (talk) 02:46, 27 November 2008 (UTC)

Thats odd
I read somewhere that enchant lengthening only stacked to 50% such as of enchanting, and blessed aura would stack to 50% even if you had say 30 in div fav (only an example). But theres nothing in the table that shows this. Did I read just a load of jibberish on this?--Sam6555 16:10, 27 March 2009 (UTC)

I dont know how to make a new category but this seems to fit. When listing the maximum effects for negative and positive stacking for effects, the max negative effect to maximum health is stated as 1. Unless i miss understand the chart this must be impossible seeing as runes of abilites (ie. necromancers major rune of blood magic) give negative health effects such as -35hp. Wich would of cource be a pointless effect. Seraphist 19:35, 18 June 2009 (UTC)

positive/negative vs. increase/reduction
These words were chosen for a reason. Increase/reduction implies that something can change an existing value, which is not true for things like attribute levels (there's a max and a min, not a stacking limit). Positive and negative not only make this distinction, but they also make the chart more clear numerically. ~Shard  04:56, 30 April 2009 (UTC)

Spirit stacking.
Am I the only one who thinks it should change? Whenever a spirit is summoned with a Binding Ritual (or Anguished Was Lingwah), it will kill any allied spirit of the same type --The preceding unsigned comment was added by 64.222.107.125 (talk &bull; contribs) at 22:29, 8 July 2009 (UTC).
 * Yes you are the only one who thinks it should change. ^_^ --Falconeye 17:58, 11 June 2011 (UTC)

Miss chance, critical hit chance, and other percentiles.
They stack multiplicatively, and don't seem to have a cap, so why aren't they on the cap and no cap list? Necromas 18:01, 16 July 2009 (UTC)
 * Because they would be copies of the "blocking" line. ~Shard  [[Image:User Shard Sig Icon.png]] 02:05, 9 October 2009 (UTC)

Recharge time?
-50% recharge time is negative??? Why would that be negative when recharge time is educed...?Also Recharge time can be increased but only by set amount that is noted in the skill ( Auspicious Incantation, Power Lock ) 95.180.76.188 17:54, 2 August 2010 (UTC)

Heal effect stacking
The Heal article says the effect stack multiplicatively, so... is that correct? K61824 01:33, 16 February 2011 (UTC)
 * if I get rank 20 prot prayers with life attunement and aura of faith, it should heal for (1.62)(2.17) = 3.5154 (times)
 * if it is reduced by every skill and condition I would then get Mark of Pain(0.67), Deep wound (0.8), Predatory Season (0.8), Defile Flesh (0.67), Lingering curse (0.8) and Malign Intervention(0.8) which is ~ 0.18387 for the reduction
 * The reduction counters the +healing to a net effect of ~ 0.64637

Inconsistent
The -25% on activation time and note 6 on recharge time disagree with the QCT and 40/40 pages. Can someone please determine which are right? -- Kirbman 16:00, 3 April 2011 (UTC)

Arrows
What is the maximum movement speed for arrows?--91.79.97.64 21:05, 28 June 2011 (UTC)

Armor stacking cap bug
Unless this bug is fixed, the armor stacking cap needs a little rewrite. Not only skills are included in the 25 armor cap, but in fact all weapon mods that are not inscriptions. Armor ratings are calculated from 6 main sources: The 'rest' category is capped at 25 armor (unless a single effect goes higher). This means, for example, if you use Stand Your Ground! with a Sword Pommel of Defense, you only get +25 armor, not +29. udas 23:41, 29 June 2011 (UTC)
 * Base armor (what you're wearing)
 * Insignia
 * Mysticism (if applicable)
 * Base shield armor (the requirement part)
 * Inscriptions (real inscriptions, not inherent mods that can be replicated with inscriptions)
 * Rest (skills, weapons mods, consumables)


 * So, are you saying the formula is:


 * ← if single-skill effects provide <=25 AR.
 * ← if x >=25.


 * And are we sure that's a bug rather than intended by the developers? — Tennessee Ernie Ford ( TEF ) 01:06, 30 June 2011 (UTC)
 * Mysticism is missing in the long line of addends (it does not count into the 25 limit but stacks, as to be expected). Your summary is correct however. –User ARTy sig.png 01:20, 30 June 2011 (UTC)
 * Yes that's the formula I believe. Ah yes, Mysticism Arty, thanks :). The 6 (7 with Mysticism) parts are added together, with only the 'rest' category having a specific cap with a possibility of single effects breaching that cap. As to your stricken part, it's easy to see how it's a bug when a shield with an inherent +10 vs fire mod works differently than an inscribable shield with "Sleep Now in the Fire". User Judas Sig.pngudas 01:23, 30 June 2011 (UTC)
 * Edited the list to move Armor of Salvation to the rest category, because it is affected by the 25 armor cap. User Judas Sig.pngudas 18:45, 30 June 2011 (UTC)

Stacking + Non-stacking results in what?
If you have a +50 non-stacking health and 2x +10 stacking health, is the net amount +50 or +70? 76.253.0.17 02:53, 14 July 2011 (UTC)


 * , i.e. +70 based on your description. — Tennessee Ernie Ford ( TEF ) 03:17, 14 July 2011 (UTC)
