Reaper

The Reaper is an enemy that spawns during a Solar Eclipse event in hardmode.

They are functionally the Wraith, but with larger numbers in their stats. However, they are nevertheless far more dangerous than a normal wraith, as they not only do enough damage to be threats to even late-game-armored players, but also move significantly faster than wraiths, and, thanks to the higher spawn rate of the solar eclipse, often attack from multiple directions at once.

Fortunately, they are quite vulnerable to knockback, and like many creatures that pass through blocks, weapons that normally don't harm enemies through blocks, like most melee weapons will damage them.

Similar to the wraith, they are incapable of ascending more than a few tiles above solid blocks. Standing on a platform several tiles above the ground or use of wings or rocket boots allows players to shoot down upon them with impunity if they are going to be surrounded.

They are immune to all debuffs and lava.
