The top three options for you in my opinion include: the skirt from Verac's dress/Dragon Legs together with Fighter torso RS3 Gold. Abyssal Torag's Whip/Dragon Defender (you may have a Guthan's set to heal you as well). Torag's Legs, Plate and Plate With Whip or Defender.

It is very effective in defense but in the majority of situations, it's very ineffective since you rarely be hit very often. This set includes Verac's Brassard and Skirt along with whip. The whole set is used for certain activities including Kalphite queen as well as barrows, or PvP.

It's a team effort. You can be an excellent keyer but without a equally good team it's useless. It's possible to play 5:5 largers with 2-3 people who are good, which includes you. That situation would be someone angry quit or who is sort of leeching/not doing anything.

I feel that having certain products aids a lot. Such as The Shadow Silk Hooded. Not just for you but for your whole team. For a single person not having it can slow down the dungeon, especially if you're trying to do like an a lever room, but the Skeletons keep on attacking the Non Hooded one.

I'd also suggest working to improve your stats. This is not just combat, but skills as well. Because time can be wasted when a keyer walks into doors and finds that you're supposed to trim vines OSRS Buy Gold, but don't have the level required so you'll need to call who can help you do this door.
