Sap's Auto curse

What is a high level monster i can use saps auto curse on(I'm in f2p)?
Does it have somewhere for me to curse from so i don't get attacked?(Fence etc)

 

I know a place where u wont get attacked.. Go to the wilderness ditch, wear full iron.. ETC, And cast it on skele's from other side of ditch.

 

you best bet is to wear mellee armor so ever time you curse you splash so you can just keep doing it over and over again of the same monster

 

Your best choice to use curse on would be to curse on the zamorak monk below the stairs in the varrock museum when you enter it straight from the courtyard. This little area under the stairs has a cage where the Monk is held, where it cannot attack you. They have a high magic defence bonus, so you should be able to curse 5 or so times until it hits, if it does just wait a second or so and you'll be able to curse again.

I recommend wearing: Iron Full Helmet, Iron Platebody, Iron Kiteshield, Green D'Hide Vambraces, Green D'Hide Chaps, and equipping an Earth Staff. Also, if you choose to wear an ammy, don't wear a Power Ammy or a Magic Ammy as they raise your magic attack bonus.

 

You can also do it on skeletons in varrock dungeon.

 

Guards would work too, or barbarians.
