The Storm Caller’s Reprisal node reads:
Your Wolves have a chance to retaliate with Storm Bolt when hit, and deal more spell damage (multiplicative with other modifiers).
Storm Bolts cast by your Wolves are affected by your Gathering Storm tree and scale with minion damage.
Okay, so I figure their bolts use their own spell damage and minion damage modifiers but other then that it uses every aspect of my own Storm Bolts, nice.
But then I look at the Gathering Storm passive tree and… there’s only four nodes total that directly affect Storm Bolt, and two of these are elemental swaps that don’t have synergy with the wolf node. So only two nodes (Jolting Strikes and Excited Bolts).
Every other node either modifies Gathering Storm itself or reads “when you expend a Storm Stack (…)”.
For example, Looming Clouds:
Whenever you expend a Storm Stack you have a chance to cast Storm Bolt at an additional enemy.
Do wolves gain a chance to also double-cast Storm Bolt? It doesn’t sound like they would, since they are not spending storm stacks (they don’t even have storm stacks).
