I roll with Piercing Orb, Star Pact, Arcane Hydra, Tele Calamity, Diamond Skin and Crit Mass.
How's Star Pact? I've tried all the meteors while leveling because that was my original theorycrafted build, but I think the aiming issue isn't worth the damage output. Is it mainly a situational skill for you, whereas Orb and Hydra is your main bread and butter?
My original plan was:
Teleport or Mirror images
Diamond Skin
Slow Time (increase AS rune)
Energy Armor
Living Lightning
Meteor (Comet, ice rune)
Idea was to stack up AS and crit chance as much as possible. Then by spamming living lightning and using the affix 'arcane power on crit', you're fed so much arcane it's possible to hold the Comet key as long as living lightning is on the field. With Slow Time and the fact that Comet also slows, additional meteors should be easier to aim than a regular meteor build.
Passives are Prodigy and Critical Mass.
Problem I had with this build: damage output isn't
that amazing to be worth all the setup you have to do in order to make the endless meteors hit. Also forced to stack critical chance to over 40% and stack at least 18+ arcane power on crit in order to do the endless feed. This is quite the problem on weapons, because arcane power on crit only exists on wands, so the attack speed isn't that great. There are 2 legendaries that do compare to an AS dagger rare: however, to get crit dmg on them with a socket is near impossible (if it even exists). Thus damage output is lower, just to make arcane power on crit work.
I was just testing some variations just now and can't decide. For now I'll keep the Archon build I currently have. I really don't feel like using Piercing Orb + Hydra, which feels very standard to me with no synergy between the skills.
