While Androxus is channeling Reversal, take the time to reload your weapon, switch targets for a moment, or escape if needed, as it's detrimental to you to attack him during this time.
Andros will typically be using a load out with the card Abyss Walker which basically heals andro whenever he uses nether step this means that Cauterize is good against andro. If you play against a team with andro and a healer caut is a good pick
Force an Androxus into a long range fight. For example, if you are playing Kinessa, and an Androxus sneaks up behind you, teleport to a distance, and open fire from there. He will either have to fight if he does not have Nether Step or run.
