Lightning Rod: “Disabling an enemy causes them to be struck by a lightning bolt.”
Tempest Defense: “Surround yourself with a Shocking Aura when disabled (stun, daze, knockback, pull, knockdown, sink, float, fear, or launch). *Deal more damage to stunned or knocked-down foes.”
Lightning Rod procs before the disables. It causes many issues.
1. Lightning Rod is blocked or evaded even though the crowd control using to disable is unblockable or undodgeable.
http://www.twitch.tv/aleriedespins/v/30181709 In this video, we have a chronomancer using Echo of Memory. The mesmer moves toward the unblockable Static Field gets interrupted and receives the damage of Static Field. What happened with the Lightning Rod?
The Lightning Rod was blocked before the disable as shown on the combat log. Additionnally, because it was blocked, it also refreshed the mesmer skill, allowing him to use Déjà Vu.
2. Lightning Rod does not benefit from the damage increase of Tempest Defense despite requiring to disable a target for it to be casted.
http://www.twitch.tv/aleriedespins/v/30182400 As seen on the video. The elementalist initially casts Gust on five golems. The damage range is 2000 to 2200 for a critical strike while using Tempest Defense. After that, the elementalist removes Tempest Defense and does the same experiment; the damage stays the same. As a result, Tempest Defense does not increase the damage of Lightning Rod. But is it because the target is not “stunned” or “knocked-down” as stated on the trait? Well, no. The elementalist used Static Field to double check and the damage on Lightning Rod remained the same. Though, the damage of the Static Field was increased, so the source of the disable gets a damage increase. Note that Tempest Defense also works on Daze, so Gust should do the same.
