Help with Galvantic Shards Mercenary please

Well, i can clear everything in a zap, except major pinnacle bosses. I can't even get the first Xesht down.

I'm following a guide from Mobylitics.com

Here is a link;

I'm following everything to a "T", except the passive skill tree. I'm using half from that guide, then half from another guide (for the energy shield bonus it applies) .

I just can't kill the bosses, I end up getting smoked eventually.
I feel like I can allocate my passive points more efficiently, I just need an experienced PoE player.

I'm level 96, please help.

Any questions, just ask.

I have 0 ES though, so feel free to adjust yourself.

Thank you, I'll check it out.

I kinda figured my situation out (killing minions easy T16, but pinnacle bosses no luck)

I had to put the "Fresh Clip" support Gem in my Shockburst skill.

Plus, "Galvanic Shards" required "conduction" support Gem for more efficient use with "Herald of Thunder".

Best regards,

Witchhunter crossbow build sucks no matter what you do.... I have quite good gears, but still can't kill any serious bosses.

It's all about shockburst rounds for bossing. Shockburst scales well with attack speed so HoWa is BIS. Also, fresh clip, martial tempo, lightning infusion, etc..

Shockburst rounds can easily reach 250K+ DPS with a little gear and melts bosses. The trick is keeping the boss shocked, which can be accomplished with stormcaller arrow bow swap & voltanic mark. Good luck to you!

Plasma blast hits like a nuclear weapon then swap to shock burst rounds and they die fast. Use galvanic shards for clearing maps.

Thank you for the tip, I'll check it out.
