Send into battle an automated SNTNL drone that continually flies through the environment and attacks enemies with its Machine Guns.
Pressing [action-skill] or [grenade] while SNTNL is active causes it to attack the enemy under Zane's crosshairs, if any.
Duct Tape Mod
The first shot fired from Zane's gun has a chance to also fire a grenade.
This skill has a short cooldown.
Additionally, Zane gains immunity from his own guns and grenades.
