Infinite Uptime Drone / Bubble Zane

Cryo-based Zane, for infinite Action Skill uptime --> maximise DPS

Requires a Rough Rider shield for Calm, Cool, Collected, and I recommend a good cryo grenade for your drone; I use a MIRV Hex

Class Mod - anything that gives +4 or +5 to synchronicity, or failing that a Legendary Executor class mod with good rolls on the stat boosts (e.g mine also has ~20% bonus DMG and +46% Jakobs crit DMG)

When level cap is raised, put points into Drone tree to get the capstone (Cool Hand -> Playing Dirty -> Violent Violence -> Seeing Red), taking points out of Best Served Cold if necessary

Secondary Augment on Shield can switch between Deterrence Field and Nanites or Some Shite, down to personal preference

Only one point in Refreshment, as health-gate means there is diminishing returns on life-leech skills
