Good guide but missing some stuff:
- Graceful gear instead of wearing nothing in gloves/boots/helmet slot
- No need to fill yak 100% with runite ore - you only need 45 runite ore which means you can take brews. With your setup you're 99% dead if a pker shows up
- Taking Dhin's Bulwark is way better (only 40m) + take amulet and stuff since every bit of defence bonus counts if a pker shows up. Drink a dose of antifire potion in case you are tped next to lava drags.
