Tempest Maw has a mod, that makes you Summon 4 Storm Sprites if you Summon a Totem.
The Summon Storm Sprite Skill has ‘Minion’ and ‘Lightning’ Tags.
The passive Node “Stormriding Companions” says, Tempest Strike will gain +3% Lightning Penetration per active Lightning Minion.
Ergo, if I equip 2 Tempest Maws and summon a totem, I summon 8 Storm Sprites, and that should give my Tempest Strike +24% Lightning Penetration, right?
I don’t really know how to properly test it out, my Lightning Penetration on the Stats screen does NOT go up when I cast them.
Can someone confirm if it works or not?
EDIT: After some small testing, seems like it works!
The character screen does not reflect any skill specific modifiers, it only shows (at best) global modifiers & that node only affects Tempest Strike’s penetration.
As DJ said, the only way to see if it works is to try it on the dummy.
Thanks for the Target Dummy suggestion. I was unsure before, because my only totem was Frenzy Totem (which affected my damage) but I remembered I also can just use a Thorn Totem somewhere far away off.
So I only looked at my crits I was doing with Ambush (the yellow numbers are easier to read) - and it seems to work!
The damage numbers I got while having Storm Sprites were consistently around 20~30% higher - which matches the expected 24% Lightning Penetration I should be getting (a bit of variance due to damage RNG is expected).
I can’t 100% for sure say, if both the Strike itself AND the Lightning Tempest are affected, tbh I find the Lightning Tempest Damage numbers hard to read, but it logically should be.
Works for me!
