Rune?
Training def bro
Obsidian sword + berserker necklace would be best if you don't have access to a dragon scim. It does carry negative attack+defense bonuses though, which could matter depending on where you're training.
Obby sword I guess, but Lost City only takes like 20 minutes tops. You can't cut 20 minutes of grinding for a d long ?
Like everyone said, you should really do lost city for the dlong
