It really is a group effort. It is possible to be a superb keyer, but without a good team it's useless. You could be able to do 5:5 larges with RS gold 2-3 good people including yourself. In that situation, you'll find someone who's either quits rage or just sort of leeching/not doing anything.
I think having certain accessories will help a lot. This includes that Shadow Silk Hooded. It's not just for you, but for all your team members. For a single person not in the loop can slow down your dungeon even if you're trying to do like an elevator room, however the Skeletons continue to target their opponents. Non Hooded one.
I'd recommend also working on your stats. Not just combat , but the skills too. It's a waste of time when a keyer is opening a door and sees maybe that you're required to trim vines but don't have the skills required, and you'll need to contact another person to do the door. Sometimes they are unable to find the knife. Also, it saves time. It's for the combat aspect of things. This is mostly for strength/defence. Only Strength is needed for the cheap OSRS gold force bar entrance or others rooms that need this ability. Later, you'll be able to defend, and use better armor and tank to take on more monsters.
