untrimmed 99 slayer cape possible?

have a friend fight the monster, then you finish it off.

 

 

 

you get the xp from the kill, not the damage

 

 

 

That doesn't work...In slayer you get the xp as you hit the monster. So you'd only get a couple xp points from finishing it off.

I read somewhere, that if you have 2 persons attacking the monster, the one who did most damage will get half the exp, and the one who finish it will get the other half.
