Polarities Mod/Speleothem

The Speleothem is a Pre-Hardmode magic weapon that has a 0.5% chance of dropping from the stalactites generated by s on impact. When used, it simultaneously generates a line of multi-hitting limestone spikes on the blocks directly underneath the cursor and spawns a falling row of spikes from the blocks directly above it (or high above its position if there are no blocks above), dealing a total of five hits. It is best used in narrow environments such as caves or housing, as reducing the vertical space above and below the cursor as much as possible helps ensure both sets of spikes hit their intended targets.

Trivia

 * A speleothem is the encompassing term for structures formed in caves by the deposition of minerals from water, including stalactites and stalagmites.
