Thinking about starting a new build based on Cast on Crit. I realized that lightning strike could be used with daggers for high crit chance and has projectiles so a projectile spell and projectile supports would create good synergy.
Was thinking:
Lightning strike+chain+cast on crit+spark+lmp/gmp/fork (+life leech or culling strike)
spark/LS leads to good +lightning damage synergy,
chain benefits both LS and spark (and -> autotargetting for the LS)
chain+spark also means this could be a single target and multitarget skill (single target should get hit by all the sparks and more sparks come out the back end due to chain)
LS and spark both benefit from projectile damage nodes
arcing blows node is 30% increased damage for the projectile part of the LS skill.
combined physical/lightning damage means reflect mobs may be less of a problem (although high crits make this worse)
I would go CI/IR and run haste and probably purity.
Here's a pretty rough draft of a passive tree; I'd welcome feedback on inefficiencies here. Seems like this could be a very high dps build though.
Passive Skill Tree - Path of Exile
Also, since I'm going CI melee, would dream fragments be a must?
My main concerns are that the build is too squishy (so many damage nodes, not a ton of ES nodes) and that I will have mana problems.
