Specimen a05 "Apex Bullfrog"

"The Bullfrog is a volcanic atrocity welded to an amphibious atrocity. It cries out for death with each gaseous, blubbering, explosive breath."

Overview
The Specimen a05 "Apex Bullfrog" is the Tier 3 reward for the 4th Boss Strike and the 15th Boss Strike. It comes pre-ranked based on the players level.

It has the two basic attacks of a normal Bullfrog plus two new attacks; Slime Ball and Corrosive Blast. The first one is perhaps the strongest attack damage wise and covers almost the whole field. However, this attack is only effective when there are no blocking units in front, since if there is a blocking unit, a target behind that unit cannot be specifically targeted. It can be indirectly hit by targeting the blocking unit or another unit near to it, but the splash damage often does not guarantee a kill. In this case, the Arcing Spew attack provides a more reliable method of indirect Damage-over-Time, but not as much potential damage output on the field. The second attack is a dedicated anti-air attack that targets one unit with added splash damage.
