Doom Scythe (絶望の鎌 Zetsubō no Kama?, Sickle of Despair) (also called DoomSickle on SNES and PS1) is a weapon in Chrono Trigger. It is Magus's 2nd best weapon (best weapon in the SNES and Playstation version) it is found in Ozzie's Fort in a hidden chamber.
Damage Boost
By using the Doom Scythe, Magus's damage will be significantly increased depending on the number of allies still standing. If all three allies are up and about in battle, Magus's Doom Scythe will be about 97% as powerful as the Dreamreaper (his best weapon, only available on the DS version). One ally down will double it, while two allies down will triple it. This applies to both normal and critical attacks.
With two allies KO'd, or if you are playing as Magus solo via Walkthrough Walls glitch, Magus's normal damage will be tripled.
Ultimately, the Doom Scythe is an incredibly strong weapon that can deal overwhelming damage if Magus is alone.
