I don't know much about the partner system in osrs slayer can anyone help me out,

Like I have an obby mauler I want to get slay exp on but its a lot harder, can I do tasks on my main and it gives the obby exp or how does it work?

I think it’s a portion of the experience, I think if your main attacks it, your pure can do the final hit? But I could be wrong

thanks for your input.

Pretty sure Climbing is correct here.

so basically I would need to be in same area and just not finish the kill

Yeah same area, and then final hit will be on the obby pure or whatever

Might also be able to lower HP of the mob on ur main and then use cannon to kill it, and just be empty / filling the cannon.

This.

thanks man I appreciate that.

i believe you have to do half the damage to get the xp

that would never work, there is no way to be sure each person would get exactly 50% damage dealt

as long as someone does at least 1 damage the slayer exp gets split in half, you see that alot when slaying in multi combat area's and someone tags your mob
