The decoys would only be statues... so, whoever you're fighting will only hit the decoy about 50 percent of OSRS gold their time (it wouldn't be able to be used in whatever player , creatures only, including some quest monsters and some of the boss ones such as the KBD or whatever they have now). There would also be some sort of way to enchant the items, either someone from the pursuit or a new bewitching charm. This way, it would work 75%-100% of the time.
When fighting multiple enemies that a decoy would completely divert you. You may only take 1 or 2 decoys at a time, for some inexplicable reason. They're too heavy. Sure you can take 8 collections of armour but only two decoys. I will try to make some sort of outline for the pursuit, do not expect too much though.
Alright, so the background is that there's some kind of monster attacking a group of individuals with the decoy knowledge. The only guy left is very old and can't move fight the monster. And there's the promise of treasure for you greedy folks out there:unsure: Requirements:Skill to kill a level 30 monster. Recommended Items: Equipment to kill a level 30 monster.
You go to the monsters lair and fight . It turns out you only rescued one person. This person is a bit proficient in making decoys. They will teach you how you can create the basic decoy from regular logs. Congrats, you've finished one measure of cheap RS gold this pursuit.
