How to use The Biggest One
The Biggest One raises pierce on every explosion from 85 to 200 and makes them all bigger:
- Main explosion: damage 10 to 25, plus 30 bonus damage to ceramics and MOAB-class bloons. Radius 58 to 74.
- Shockwave: ceramic bonus from +2 to +20. Radius 87 to 111.
- Stun blast: radius 29 to 37, and it now stuns blimps briefly: 0.4 seconds for MOABs, 0.2 seconds for BFBs and DDTs, 0.1 seconds for ZOMGs.
With the 5-0-2 crosspath, the burn deals 65 damage per tick instead of 12.
When to buy it
The Biggest One costs $36,000 on Medium. It is a strong and simple global popper for big groups and a reliable blimp stunner, but it has little single-target damage. Aim it so each blast covers as much of the track as possible, usually on a tight loop or near the entrance.
Striker Jones is the only real hero choice, because his attack speed and black-popping buffs are hard to replace. On harder maps, an Engineer's Overclock helps it catch super ceramics and DDTs consistently. Pair it with a single-target blimp killer such as MOAB Eliminator.
- 5-0-2: the huge burn makes this the top choice on long tracks.
- 5-2-0: faster attacks for multi-lane maps or when you need more stuns.
Late game and bosses
In CHIMPS, The Biggest One clears super ceramic rounds and stalls blimps well with the right support. Against BADs and boss events, its lack of single-target damage makes it a support pick rather than a carry.
Is it worth it?
Yes, as a group popper and stunner. Compared with Pop and Awe, it is easier to use but deals less damage to blimps. Compared with Blooncineration, it is better at popping ceramics but much weaker against MOAB-class bloons.
