What is the BEST Vaal GEM Boss Killer

Hi i am currently playing a cyclone coc discharger, and i was thinking what i can do against bosses since my single target isnt really amazing (I am a weapon of MASS destruction :))

I tried a it around with frenzy but didnt like it to much.

So I was thinking about using a Vaal Gem, i could do it in a 3link what would be the best single target options here.

I was thinking about Vaal Fireball GMP ConcEffect but maybe you can give me your thoughts what would be the best options

Vaal Spark + Trap + any projectile gem (lmp/gmp/fork) + lightning pen is an incredible good boss killer...bosses with a big hitbox like vaal get hit by almost every single spark and if you roll a crit every spark hits critical...one trap did like 30% dmg to vaal merciless and the vaal spark i used wasnt even on my level...

give it a try...sounds sick when you crit btw.

Vaal Molten Shell vs Shock and Horror.

Laugh.

its more like killing a single target shock and horror arent hell of a fun anyways :) what you guys think about this phys vaal gems (my dagger does 170 pdps with 8.xx crit) thinking about vaal doublestrike and so on i do high spell damage though .. rly dont know spark might be good but dont think its a one shotter for most bosses ? still could be good since i do mor lightning damage

I've found Vaal Summon Skeletons to be good for finishing bosses. But that is admittedly with a summoner build.

With summoner or aura build: Vaal skeletons(multistrike, faster attacks + whatever else)
With crit spellcaster: Vaal spark + GMP + trap + added lightning(or penetration)
Against fast hitting bosses: Vaal molten shell.

I don't find any bow vaal skills that impressive. Puncture alone beats them all for single damage potential.
