Blur/displacement and concealment.

[DJGravity]

Do the blur/displacement spells stack with items or enhancements that grant blur effect/concealment?

No, its all the same type of bonus, concealment.

[Enoach]

As stated Concealment bonuses are not suppose to stack

Blur and Displacement Spells don't stack <- Highest is used

Dusk, Blurry and Lesser Displacement don't stack with each other <- Highest is used

Now the first group and second group are not suppose to stack with each other and for the most part they don't.

However, there is a situation where Displacement spell and Lesser Displacement (equipment) do stack giving a potential of 75% concealment but if Blur is also cast it changes the stacking to not being a stacking bonus. Based on this it appears the two Displacements are not WAI.

Source/proof?

Shadow Walk doesn't stack with displacement either since it's also a concealment bonus.

Below is just a copy paste from another thread. You can have dodge, concealment, and incorp, one of each. Multiple sources of each type do not stack. And they are multiplicative not additive. ie: I have 10% dodge and 50% displacement. My chance is 50% from the displacement, and then 10% of the remaining 50%, so total 55% miss chance. Copy paste follows of different sources and type, not sure if it is complete:

Personal Concealment:

Item effect: Dusk. 10% concealment.
Item effect: Smoke Screen. 20% concealment.
Item effect: Blurry. 20% concealment.
Monk finishing move: Dance of Clouds: 20% concealment. Works on friendly NPCs.
Spell: Blur. 20% concealment.
Item effect: Lesser Displacement. 25% concealment.
Spell: Shadow Walk. 50% concealment (lost if you interact/fight).
Spell: Displacement. 50% concealment.
Blindness: All opponents are considered to have total (50%) concealment to the blinded character.

Area of Effect Concealment (cannot be negated by true seeing):

Level 1 Spell: Obscuring Mist. 20% concealment.
Level 2 Spell: Fog Cloud. 20% concealment.
Level 3 Spell: Stinking Cloud. 20% concealment.
Level 4 Spell: Solid Fog. 20% concealment.
Level 5 Spell: Cloudkill. 20% concealment.
Level 6 Spell: Acid Fog. 20% concealment (Blocked by Freedom of Movement and Red/Purple named are immune).
Level 8 Spell: Incendiary Cloud. 20% concealment.

Incorporeality:

10% - Feywild Tap (Elf enhancement)
10% - Ghostly (item enchantment)
25% - Ghostly Essence (Shadar-kai enhancement)
25% - Shadow Veil (Ninja Spy 3rd core enhancement)
25% - Shadow Form (Shadowdancer epic destiny)
25% - Shroud of the Wraith (Pale Master 4th core enhancement)
25% - Walk with the Spirits (Primal Avatar epic destiny)
35% - Shroud of the Wraith with Improved Shrouding (Pale Master T5 enhancement)

So..if I had the dusk heart trinket..and then cast blur and displacement.. Which one works? Which one should I use? Also..when doing sp pow, on items,does highest comply or do they stack..example would be ifi had weapon will 138 fire then a cloak with 50 fire..they stack?

Wait - what? Since when? :confused: This is the first I've ever heard of it...are you sure you're not confusing Lesser Displacement with Ghostly?

The usual rule is: same-type bonuses do not stack; different types of bonuses do. Simple example: having two items with enhancement bonuses to the same stat or Spellpower don't stack (only the highest applies); having one item with an enhancement bonus and another item with an Insightful bonus will stack. So when shopping for gear, pay attention to the descriptions to be sure you're mixing-n-matching bonus types correctly.

Note that gear doesn't always stack with spells or class abilities - again, it depends on the bonus type: e.g., Divine Might is an Insight bonus to STR, so it won't stack with Insightful STR gear; Bull's Strength is an enhancement bonus so it doesn't stack with an enhancement STR item, but Ram's Might is a size bonus (+2 STR), so it will stack with an enhancement bonus (either Bull's STR or gear).

They don't stack. Not unless the cloak's power is insightful.
As for blur, displacement and dusk heart, neither of them stacks with each other. Best is displacement and that's it from that field of defence.

TL/DR - Blur/disp/dusk don't stack but can act as backups to each other. SP power doesn't stack for like bonuses.

No, they don't stack but there is no harm and some benefit to casting blur, then displacement and wearing a dust heart and that is because of spell durations. You are essentially creating a backup for yourself. I do know - especially in epic content - exactly when my displacement runs out because I suddenly start taking a lot of damage and that can be mitigated if I have blur running as well.

So if you cast a 10 min blur and a 2 min displacement you won't be caught unprotected when displacement runs out because you still have blur running. And if you get dispelled or run into a beholder you will still have the dusk heart to conceal you.

As for the SP power, no they don't stack. Like bonuses don't. Now, if you had an insightful SP bonus then yes, that would stack with a standard one because it isn't a like bonus (enchantment v insightful).

Short answer: all of the above. :cool:

As one example, look at slarden's warlock thread (https://www.ddo.com/forums/showthread.php/460700-Pure-Casting-Warlock-DC-Eld-Blast-Build) and the breakdown of his Spellpower.
