The Celebration is a post-Golem launcher sold by the Party Girl; the Celebration Mk2 is a post-Moon Lord drop with higher listed damage, faster firing, varied rocket effects, and a 50% chance to save ammunition. Both fire rockets and neither damages the player, but their projectile patterns and interactions with rocket effects differ. The comparison below follows the Official Terraria Wiki item pages, which cover Desktop, Console, and Mobile; exact details can vary by version.

How do you get each launcher?

Celebration

After defeating Golem, the Party Girl sells the Celebration for 80 Gold. That makes it available earlier in progression than the Mk2. In Desktop 1.4.0.1, its acquisition changed from a Moon Lord drop to a Party Girl purchase after Golem.

Celebration Mk2

The Celebration Mk2 is a Hardmode weapon obtained from Moon Lord, with a listed 20% drop chance from Moon Lord or the Moon Lord Treasure Bag. Its listed drop rate was reduced from 2/9 to 1/5 in Desktop 1.4.5.0.

How do their listed stats compare?

Stat Celebration Celebration Mk2
Listed damage 25 ranged 50 ranged
Knockback 4 (Weak) 10 (Extremely strong)
Critical chance 4% 4%
Listed use time 30 (Average) 6 (Insanely fast); actual rocket fire rate corresponds to use time 8
Listed velocity 15 17; this single figure does not capture actual projectile velocity
Ammo conservation No saving chance stated on the item page 50% chance not to consume ammunition

These listed figures are from the Official Terraria Wiki item pages, not a controlled damage or firing-rate comparison. The Mk2’s rockets are not fully described by its listed use-time and velocity values: its firing rate corresponds to use time 8 and is not affected by attack-speed modifiers. Its effective velocity is 27 for green rockets and 24 for the others, before their distinctive trajectories change movement. The page cites Desktop 1.4.5.6 source code for some behavior details.

What do the launchers actually fire?

Celebration: two fireworks per rocket

Each rocket consumed by the Celebration produces two firework projectiles. The launcher disables most special rocket functions, so the ammo’s normal behavior does not necessarily carry through.

Celebration Mk2: seven cycling rocket types

When the attack button is held after the first shot, the Mk2 cycles through red, orange, yellow, green, blue, purple, and pink rocket types. Their behaviors differ: red rockets gain piercing after 0.33 seconds, green rockets gain homing after 0.33 seconds, blue rockets fire two at once, and purple rockets fire three at once. The Mk2’s tooltip reads, “All good things end with a bang… or many!”

How do they interact with rocket ammo and terrain?

The Celebration disables most special rocket functions, including tile destruction from Rocket II and Rocket IV, liquid placement or removal, and cluster fragmentation. The Mk2 retains tile-destruction effects from some ammunition, but it cannot place or remove liquids and Cluster Rockets do not function normally with it.

Which one should you use?

Before Moon Lord

If you have defeated Golem but not Moon Lord, the Celebration is the one of these two available through ordinary progression. Its purchase price is 80 Gold, and it fires two fireworks for each rocket used.

After Moon Lord

The Mk2 has the higher listed damage and knockback, a faster actual firing rate than the Celebration, multiple projectile behaviors, and a chance to conserve ammunition. Its distinctive effects and ammo interactions matter, though: it is not simply a drop-in upgrade for every situation, especially if you rely on a rocket’s normal special function.

Version and platform notes

The Official Terraria Wiki entries label both weapons for Desktop, Console, and Mobile. Some history and behavior details are explicitly tied to Desktop versions, including the Celebration’s Desktop 1.4.0.1 change and the Mk2’s Desktop 1.4.5.0 drop-rate change. If a precise stat or interaction matters in your world, check the item behavior in your game’s version.
