Too bad there is only one MI Off-Hand that can reduce 1.5-sec cool down. Is there another item that can reduce more cool down? (I know some helmet gives you 4-5% cool down).
Also, does Storm Totem benefit from “faster casting” stat?
Here you’ll find all Skill modifiers for Storm Totem.
The one you’re looking for is probably the conduit which reduces the cooldown by another 0.5 seconds.
There is also Stormreaver (2-handed axe) which reduces the cooldown by 2 seconds.
There are two main ways to build around totems. The conduit is indispensable in both. You either go for melee (or primal strike caster) hybrid with Stormreaver 2h axe or go for maximum totems with Groble Sky Effigy offhand and Stormstrife dagger. Here’s the latter. There’s also a no-green cheaper version with a gun but limited to 3 totems.
