Sniper critical hits freeze enemies for 1.6 second(s) and apply water affliction, dealing 21 base water damage per second for 3 seconds
For this build you need one of a select few sniper rifles. Blastotron 9000, Boom Bow, Triple Tap, Vacuum Tube Rifle(unfortunately only nature damage). You need to roll them to at least 50% critical chance. When you critical you will freeze your target for what it says is 1.6 seconds but seems more like 4. You can use this to support your team by freezing high value targets. Smashers, Huskys, Propane, Beamer, Takers. As soon as you freeze one switch to another and try to keep all high value targets on the field frozen.
