Tired of tooting your own horn?
When equipped, the Diamond Horn grants the Energized Hornmod, which allows the player to build one tile further. The Diamond Horn cycles between 3 items — unequipping and re-equipping it transforms it into another horn.
1st form (Diamond Horn): Retextured version of Unicorn Horn with a similar punch effect with Focused Eyes.
2nd form (Diamond Horns): Retextured version of Demonic Horns (MAHHTIN's moderator item), but thinner with a punch effect similar to a Heavenly Scythe.
3rd form (Diamond Devil Horns): Retextured version of Helmet Of Darkness horns with an original new punch effect that highly resembles to lightning.
Trivia
On the 1st of June 2017, a duplication exploit was found for the Diamond Horn involving the Phone Booth which resulted in 1300 players being banned. 600 of those were perma-banned. Some exploiters had their Diamond Horns removed and were unbanned.
