When do PvP Modifiers take effect?

So, I understand that our PvP gear only kick in during combat. Our PvP talents are always active, and our PvP sets are active at full effect, until combat.

So, my question is:

When do PvP modifiers take effect? If it says my Arcane Blast will deal 45% additional damage, does this only take effect when I hit a player, or always active during Warmode?

With that being said, my Magi’s Spark is now reduced by 50% in PvP (boo, since only the first tick counts), so does that mean it will always be 50% in Warmode content or only when I hit a player?

Thanks,

It’s active when you’re acting up on or being enacted on by another player.

PvP gear and ability/talent modifiers both take effect the same times.

Your PvP gear and your abilities and talents will use their PvP scaling when:

  • You are in any instanced PvP area, such as a battleground or arena.
  • When you are in any free for all world PvP area (not 100% sure on this, and not 100% sure this applies to older expansions).
  • When you have entered combat with another player in the open world (you attack them, they attack you, or you heal a player who is in combat with another player).
  • You attack or heal a PvP target dummy (useful for checking PvP stats).

Like you already mentioned, PvP talents are always in effect in the open world while in war mode, or in any instanced PvP area.
