Bomb Description: Blasts bombs in large, random areas around the hero.
X42-Rocket Description: Shoots enemies randomly, dealing area damage. Each rocket contains multiple bombs.
Named Bomb, and not the more logical bombs, it's core to almost every build in the game. Bomb is S+ in early, mid, and late game normal and hard mode. You want them in Faction Wars, Hero Clash, Dungeon, and Adventure.
For that reason, it's worth investing Super Tokens into them to get to the 5* forge. I personally invested 3k into them - after they came around in Arena, I used 3,000 Super Tokens to upgrade to 4* forge.
The 3* forge "Amplify" is a strong global buff that adds 2.5% Area of Effect, one of the more sought-after utility stats in the game.
They fall to B tier for Nightmare Mode, where you want the stun from the 2* forge and can be used to round out a build. They are B in Boss Brawl because the AoE is wasted.
Area of Effect and Cooldown are the two statuses that dramatically improve the Damage Per Second (DPS) of Bomb. Projectile increases and projectile speed also help.
They evolve from Area Tome, which synergizes well across all game types, making it easy to evolve.
