What you need:
Knife (for cutting through the web if you are coming from ardougne)
Theory behind it:
To gain EP, you need an item that is 75k+ in value, with the lowest alch value, and currently, is it the yew seed. Because it has such a low alch value, you will keep very cheap items before it in BH+1 worlds. If you have a weapon such as a javelin, thrownaxe, knife, or dart, and you put auto retaliate on, you will release your weapon when attacked, and when you die, you will keep the Saradomin page.
Tip for pkers:
If you have a recoil that's halfway used, it's completely useless, so you can bring the charges down to a low number and use that instead. There's certain ways you can exploit people gaining EP in this way and make them drop their yew seed, but if you have a recoil, it's 100% effective. A recoil reflects 10% of the damage rounded up, so if you have 80 hp, 8 charges or less would be perfect, but you'll still make it with around 10 charges since they won't hit a multiple of 10 every time.
A popular spot:
Upstairs the ship in level 56 wilderness
People rarely go there to pk because it's impossible with all the stairs and ladders. Nobody on ground level can see you since you are upstairs. No matter where you get attacked from, your rune dart will be able to hit them, so you can't be farcasted.
Your target will have one hell of a time trying to reach you since there's a lot of pkers around this area. The only downside is that occasionally, a pker is curious and goes there.
My favorite spot:
Center of the lava maze
Nobody EVER goes here. Nobody can see you from the outside since you are so far in. In the rare case that someone decides to go exploring in a bh world, you can see them from far away and you got several minutes to log. Downside is that if someone comes in here and farcasts you and you don't drop your dart, you lose the yew seed.
Another good spot:
Red Dragon Isle
Before you get to me, you have to get through a pack of red dragons! And then I log.
