Rock Tunnel Guide
Flash is optional but strongly recommended. The cave is pitch black without it and navigating blind means bumping into every trainer and wild encounter along the way. HM05 Flash comes from Oak's aide on Route 2 after catching 10 Pokemon. Any compatible Pokemon can learn it.
Wild Pokemon are level 13-17 walking. Trainers carry teams up to the low 20s. A party around level 20-23 handles it comfortably. Bring some Potions and Repels since there is no Pokemon Center inside. Rock Smash encounters here range much higher if you have it.
Depends on what you're after. Repels block encounters below your lead Pokemon's level, so a level 20 lead in Rock Tunnel filters out the common level 15-16 Zubat while still triggering rarer spawns. If you're grinding, skip them. If you're just passing through, they save time and healing items.
Only Rock Tunnel is completely dark without Flash. Every other cave in FRLG is fully lit by default. Flash itself comes from Oak's aide on Route 2, and you only need 10 Pokedex entries to claim it.
Escape Rope warps you to the last entrance you used and costs 550 at most Poke Marts. The move Dig does the same thing for free if a Pokemon on your team knows it. Both work in any cave or dungeon in the game.
