Boss Abilities

Boss Abilities are the four different abilities that can be used (at the cost of Bloonstones) to aid the player in fighting the various Boss Bloons. The four Abilities are Boss Chill, Boss Blast, Boss Bane, and Boss Weaken. All of these are Special Items and can be seen in the "Special Items" tab of "Monkeys and Items" button in the map menu. The only way they can be earned free is through Bounty Cards or events such as Monkey Teams or Mini-Land Grab that reward Boss Abilities. In Mobile, the other option is to get them from Bloon Spy Event.
