looking for a ohk or glass spears

i currently play on a private server pretty sure its 1.69 and i like to solo everything so i am looking for a ohk or glass spears that do alot of damage so i can solo glass regina so i can get set up is there a hfs file i can switch to make this happen? I used to do the whole injection thing for a console on the original vindy back in the day and hfs file swapping so i kinda know how to do it but its been awhile so if anyone could gimme a hand on how to do this on private server i would be greatly appreciated. Also if there is like mods like bust increase and different armors would also be cool like we used to do with a console.
