On the Americas server 4p leaderboard, this guy ncg darenniisama (wiz hydra boss killer) has cold% on his bracers, and uses a spectral blade variant (i think for barrier blades shielding). Can anyone explain why he is using cold? I was thinking perhaps it is so that his archon beam doesnt interrupt manald heal procs from hydra?
He saves one other spell/element (cold) by doing that, since double lightning (Hydra+Archon) is pointless. Archon does no damage in comparison to Hydras for a boss killer; the main purpose of Archon is to get the IAS stacks and Stricken stacks. The damage comes from Hydra anyways. Archon cannot interrupt Hydra MH procs though since Hydra *always* has priority and basically "overrides" any other spell.
It's a HC variant I guess since he's gone for Barrier Blades and the Spectral Shard in cube to give him high attack speed and proc the barrier blades. Of course it's missing 60% damage from Starfire in cube that way. But yeah, HC. And damage still seems enough for GR110 at paragon 1700 so they're fine...
The barrier blades paired with the Fragment of Destiny in the cube, just stacks stricken so much faster. And the cold% is i think so that the wiz can help the barb pull mor mobs, without stunning them.
