Ceramic Bloons can naturally spawn from the Storm. On Round 7 (Player 2) and Round 8 (Player 1), a single Ceramic always spawns. Two Ceramics always spawn on Round 19 (Player 2) and Round 20 (Player 1). Additionally, Precursor Bloon can summon Ceramic Bloons during a match.
Ceramics apply decent pressure to the opponent if they lack single-target damage. Multiple Ceramics can also be paired with lots of Large Bloons to pressure the opponent to consume a high-damage board clear such as Thunder Druid or Super Monkey Storm.
For early-game, Super Monkey does enough damage to pop an entire Ceramic Bloon with all 3 ammo.
Ceramic Bloons cost in groups of 5 Gold, which conveniently allows Gwendolin to use a Fireball and reach back her old Bloontonium amount. Likewise, two Ceramics are enough to access her Heat It Up efficiently. Adora also benefits from Ceramic's groups of 5 Bloontonium, for both her Orbs of Light and Ultimate Sacrifice.
