Stormblast bolts

its explosive shots socketed in mirage archer or mirage deadeye, so you can just

• dodge roll (mirage archer)
• shoot galv shards (mirage deadeye)

to spawn the clone that explodes bolts with explosive shot

in the vid you posted its mirage deadeye, so he spawns it by shooting galv shards

this is a pathfinder example with mirage archer https://youtu.be/h8NBhAX5Kss?si=3xUikex_-85DQhUz

if you are interrested, this is a pretty minmaxed character, with 1.9k life and 6k es now and enough damage for anything solo

i think the only thing i could improve is with a high % rare jewel boost adorned which is just way to expensive
