Just west of Edgeville, a crack in the earth surface opens up. Cockroaches have begun spilling out. Big ones! There might be something big and nasty making them down there. Do you have what it takes to fight your way down to her?
Face off against cockroach nymphs, workers, and soldiers through a good variety of rooms until up're ready to breach the chamber of the queen. The fight will be icky, but the rewards tailored towards F2P players will be worth it.
The rewards could include...
Roach Boots, level 30 tribrid footwear that gives +1 Strength, Ranged, and Magic.
Regal Roach Vestaments, level 30 magical armor for the F2P mages with slightly lower stats than Mystic robes. It also makes you look like a big roach with wings.
Roach Meat, disgusting meat that can be cooked at level 58 Cooking to restore 15 Hitpoints. Tastes better than it looks. Barely.
Roach Milk, an absolutely foul cooking ingredient you can ask the Head Chef in the Cooking Guild to churn into Roach Cheese for you. A slice from the wheel lowers stats, but restores 4-6 Prayer. Tasty!
And included is a rare 1/32k drop of the fabled...Rune Scimitar. F2P UIM playerd in shambles.
Let's see a decayed form of the Stronghold of Player Safety make a comeback as a raid introduction to F2P! Maybe. You're disgusting if you want Roach Milk, after all.
As usual, comment on thoughts for the stuff. You can now downvote this because I had the audacity to suggest giving F2P something again.
