When against a team with a Androxus who pressures you a lot, place an illusion behind a tank just as a precaution, if you get cornered by him in a fight, simply teleporting to that illusion will save you, as Androxus can only deal with single targets
Save your Fireball when Seris is healing her tank. Combining that with Cauterize on your flamethrower, your tank will get healed less, so he will require more healing attention, as such, reducing the survivability of their tank and other teammates.
