Rockets

Rockets are a Hardmode, post-Plantera form of ammunition, sold by the Cyborg. Most Launcher-type weapons use Rockets as ammunition.

There are four varieties, each with two significant defining traits: area of effect, and the ability (or lack thereof) to destroy tiles. Rockets I and II have a small area of effect, closest to that of a Bomb or Grenade, while Rockets III and IV have an area similar to the blast radius of Dynamite. Rockets I and III will leave tiles unaffected, while II and IV will break blocks and furniture in their blast radius (except for explosion-proof objects).

A rocket's splash damage will harm its user if they are caught in the blast radius. These explosions will not affect other players unless they have PvP enabled, however.
