Do Spell-Pierce items stack ?

[Aeoric]

i.e. the 5% spell pierce on

Jacina's Sash, Traldors Oracle and Atlantis Tablet

do they stack to form 15% spell pierce ?

also what is the actual effect of this ?

15% resist's negated ?
15% chance that all resists are negated for that attack ?
15% extra damage ?

15% resist's negated ? < this one

also they do stack but afaik next patch its limited to max 10% peirce

 

[Elvo^Rylu]

It's capped at 10% in this patch.

And yes, it negates the set %-number og resists.

 

[Glacius]

Capped at 10%..? well if u got Traldor..and u use the lvl 10 ability ..u got 10% ..means u r caped?

 

[Flimgoblin]

10% cap from all sources - be they chants or not

subtracts from item based resists so if someone has 6% spirit resist on their equipment (maybe they don't fear the smite!) then 10% resist will only reduce their resists by 6% even if they have a 24% spirit resist buff from those evil bastard wardens

- Spell Piercing bonuses now correctly modifies resistances downward instead of upward, for direct damage spells, debuffs and damage over time spells. A level 50 character can not have more than 10% Spell Piercing effect up at any one time (from items or spells); any Spell Piercing over 10% is ignored (previously Spell Piercing was "capped" at 25% for a level 50 character).
patch 1.70

which is why lire bugs everyone to use it all the time

some cleric don't cap range %

 

[RaiderX]

thanks for the info, I'd wondered this myself

But in realistic terms - do you see any major difference with 10%
spell piercing:

Is it an always-on ability or a "use once for 10 mins every 30 mins"
type thing ?

For a nuking class, do you see a discernable impact on damage ?

Is it worth trying to factor Jacina's, Traldors and/or Atlantis Tablet
into an SC template (all have pretty ropey util imho) ?

Are there any other items that give spell piercing ?

 

[Tilda]

Yes you do see a major difference. In normal RvR, its like people havent capped their resists VS your dammage.
Its always on, if its on the item, if its a chant, such as CS, then its every 10 mins iirc.
Yes its worth it for a nuking class.
Jacinas yes (get it with a matter cabby + lvl 20 earth wiz this patch before its nerfed) I'd say no to the otheres.
Go for Tartaros, its got an mlc2 charge which helps more in NF.
Similarly, GoV is nice, good bonus stats.

I think A standard caster setup uses tartaros, GoV, Jacinas, Zo'akart, Mad tales and erinys.

Yes, Erinys does, so does BoM staff, cloudsong charge, Crown of Zalhur charge and probably some others.
