This weeks featured guardian is: Primadrake!
Primadrake has Bold and Haste, which means that for every AOE hit, it gains speed! For a bit of Focus, you can easily evolve Primadrake to its final state: Paradrake.
Place Primadrake in a place with tightly grouped Corruptors and watch it evolve into a firehose of destruction!
