Interestingly you can encounter ocean life it is important to go to any Runescape port

For each 28 runes you earn you'll get 308 runes as well as 99 RC. Each rune is sold for 5 gold each. It costs 308*5 = 1540 for 1 load OSRS Power Leveling. If you load 100 times and you'll earn 154000gp. Quick money and, If the mage you have is one you can get the runes free of charge or cheaply when the essence is bought. It's free if you purchase the essence via tele from Aubry, which is the easiest and cheapest method to boost your RC.

Now that I have keyed many times (since 70 dg) I have compiled an outline of keyer and raider. This is my recommendation however, please make it better. The mark option to control gds, skill door, and the skill rooms.

Gatestone is a tool to secure certain items that you as keyer cannot open. Prioritize rooms and gds that the whole team needs first, skills rooms/doors/keys. If doors that are not locked were opened, you should avoid the group. Memorize keying positions, (try writing it down it can help, open a maps and visualizing where key doors/gds/rooms etc are on the map).

Two gds Do you have two Gds? Prioritize them. Then evaluate your map to decide which one will lead you to additional doors. A free gate? Use it to reverse track doors you believe will be chained to the de. If you require food, you can request your team members to drop at ggs or shout "ggs heal" depending on your teams speed. Team in gd but need door open? Gate the door needed and provide one team member with the gate for free buy osrs infernal cape. Then ask for the keyer to unlock the door.
