The Heavy Rebar is a melee weapon in Dying Light. Although the Rebar is pretty powerful, it does take a lot of stamina for one hit which can be a con to using this powerful weapon. Regardless of the amount of stamina it takes for one hit, it still gets the job done!
The Rebar only appears after defeating a Goon and normally appears with around 200 damage and 1 handling regardless of which type of goon is defeated and how far the player has progressed. They cannot be repaired after breaking and will fully deplete a player's starting stamina per swing. Thus, their usefulness quickly fades at higher levels. However, throwing the Heavy Rebar regardless whether it's fully repaired or needing to be repaired will still one shot most zombies.
