Bomber

Bomber kicks off the secret tier, and the name fits the role: a Tier S heavy attacker for the deep endgame. At 1 in 307 million it is a pull only well-built accounts will see, and reaching it signals your luck stack is genuinely strong rather than aspirationally so.

Equip Bomber as front-line damage the instant it lands. The secret tier is where rarity and power finally move together again, after the ethereal band put the awkward SlimeSlimeSlime and Puffy entries between rarity and Tier S. Bomber is the affordable entry point to the secret band, and once you have it the next steps to UFO or Blackhole feel reachable rather than theoretical.

After Bomber, the secret tier becomes a real grind rather than a daydream. By the time UFO or Ember joins the loadout, Bomber has paid for its luck-window cost in zone clears many times over. Until your stack genuinely supports billion-to-one math comfortably, Bomber is the highest realistic damage slot most accounts will ever see in active play, and that makes the pull a meaningful inflection point.
