Pokemon Ruby Sapphire Rain Badge Guide

Mossdeep to Sootopolis. This phase covers Dive routing, the Seafloor Cavern, the final Maxie or Archie battle, Groudon or Kyogre, the Cave of Origin, and Wallace.

Route Map

Phase 8 is the HM water maze phase. Bring Surf, Dive, Strength, and Rock Smash before committing to the Seafloor Cavern.

Dive Route Setup

Teach Dive after receiving HM08 from Steven. From Mossdeep, surf south through Routes 127 and 128, then use Dive on Route 128 to search for the underwater entrance to the Seafloor Cavern.

Dive Routes And Underwater Grass

Dive turns the ocean floor into its own encounter layer before Seafloor Cavern and Sootopolis.

Pokemon	Versions	Method & Rate	Notes
Clamperl Water - Lv 20-35	Ruby & Sapphire	Underwater seaweed 65%	Available in the listed area during this phase.
Chinchou Water/Electric - Lv 20-30	Ruby & Sapphire	Underwater seaweed 30%	Available in the listed area during this phase.
Relicanth Water/Rock - Lv 30-35	Ruby & Sapphire	Underwater seaweed 5%	Required for the Regi puzzle later.

Bring Repels if random Tentacool and Wingull encounters are slowing you down. Also bring Escape Rope or enough healing to leave safely after the cavern if your team gets worn down.

Seafloor Cavern

The Seafloor Cavern requires Strength and Rock Smash. The boulder puzzles are the main friction point, so bring the correct HM users before entering. If you reach a room that seems blocked, reset the boulders by leaving and re-entering the room.

Seafloor Cavern

Pokemon	Versions	Method & Rate	Notes
Zubat Poison/Flying - Lv 28-35	Ruby & Sapphire	Cave walking 90%	Available in the listed area during this phase.
Golbat Poison/Flying - Lv 33-35	Ruby & Sapphire	Cave walking 10%	Available in the listed area during this phase.
Tentacool Water/Poison - Lv 5-35	Ruby & Sapphire	Surf 60%	Available in the listed area during this phase.
Zubat Poison/Flying - Lv 25-30	Ruby & Sapphire	Surf 35%	Available in the listed area during this phase.
Golbat Poison/Flying - Lv 30-35	Ruby & Sapphire	Surf 5%	Available in the listed area during this phase.

Wild encounters include Zubat/Golbat lines and water/cave options depending on floor and method. The dungeon’s important job is story progression, not team building, so do not risk a core team member for a low-value catch.

Final Maxie Or Archie Battle

At the deepest point, Ruby players battle Maxie and Sapphire players battle Archie. This is the final villain leader battle before the legendary awakens.

Ruby’s Magma fights lean Fire, Ground, Dark, and Poison. Water and Ground coverage are excellent, but keep Grass types away from Fire threats. Sapphire’s Aqua fights lean Water, Dark, and Poison. Electric and Grass coverage are strong, but watch for Sharpedo-style mixed pressure.

After the battle, Groudon awakens in Ruby or Kyogre awakens in Sapphire, and Hoenn’s weather changes dramatically.

Sootopolis City

Go to Sootopolis City after the weather crisis begins. If you have not visited before, enter through the underwater route: Dive outside the white rock ring, surface inside the city, and heal.

The Cave of Origin opens as the story’s next step. Save before going deep if you care about catching the legendary.

Cave Of Origin

Pick up HM07 Waterfall inside the Cave of Origin. You cannot use Waterfall outside battle until Wallace is defeated, but you need the HM for the final route to the Pokemon League.

Cave Of Origin

Pokemon	Versions	Method & Rate	Notes
Zubat Poison/Flying - Lv 28-35	Ruby & Sapphire	Cave walking 60%	Available in the listed area during this phase.
Mawile Steel - Lv 30-35	Ruby only	Cave walking 30%	Available in the listed area during this phase.
Sableye Dark/Ghost - Lv 30-35	Sapphire only	Cave walking 30%	Available in the listed area during this phase.
Golbat Poison/Flying - Lv 33-35	Ruby & Sapphire	Cave walking 10%	Available in the listed area during this phase.
Groudon Ground - Lv 45	Ruby only	Static legendary 1 per save	Story legendary for Ruby.
Kyogre Water - Lv 45	Sapphire only	Static legendary 1 per save	Story legendary for Sapphire.

At the bottom, Ruby players face Groudon and Sapphire players face Kyogre. Groudon is Ground type and brings harsh sunlight. Kyogre is Water type and brings rain. Status is the safest capture support: Sleep and paralysis are better than raw damage. If you do not want to use the Master Ball, bring Ultra Balls, Timer Balls, healing, and a bulky resist.

If you knock out the legendary and save afterward, you lose that capture in the original games. Save first.

Team Recommendations

Role	Best picks for Wallace	Why it matters
Grass offense	Sceptile, Breloom, Vileplume, Ludicolo	Hits most of Wallace and destroys Whiscash
Electric offense	Manectric	Excellent into Luvdisc, Sealeo, Seaking, Milotic
Whiscash answer	Grass type	Electric does not affect Ground/Water
Special wall	Tentacruel, Gardevoir, bulky Water	Helps into Milotic and Sealeo
Avoid relying on	Fire, Rock, Ground only	Wallace resists or punishes them

Must-Grab Items (Phase 8 Master List)

Item	Location	Why You Want It
HM08 Dive	Steven’s house after Mind Badge	Required to reach Seafloor Cavern
HM07 Waterfall	Cave of Origin	Required to reach Pokemon League
Groudon or Kyogre	Cave of Origin	Version mascot legendary
TM03 Water Pulse	Wallace reward	Reliable Water move with confusion chance
Rain Badge	Wallace reward	Lets Waterfall work outside battle

Gym Strategy - Wallace, The Water Leader

Wallace uses Luvdisc Lv. 40, Whiscash Lv. 42, Sealeo Lv. 40, Seaking Lv. 42, and Milotic Lv. 43. His reward is the Rain Badge and TM03 Water Pulse. The Rain Badge lets you use Waterfall outside battle.

Manectric does a lot of work, but it cannot hit Whiscash with Electric moves because Whiscash is Water/Ground. Bring a Grass move specifically for Whiscash. Breloom, Sceptile, Vileplume, and Ludicolo all solve that slot well.

Milotic is the ace and the reason the fight can drag. It is bulky and can heal or stall depending on its set. Save your strongest super effective pressure for Milotic and avoid letting your Grass answer get worn down by the earlier team.

After The Badge

Teach Waterfall and prepare for Ever Grande City. The main story path is now open: surf east/south to Route 128, reach Ever Grande, climb the waterfall, and enter Victory Road.

Version Note Summary

Ruby gets Groudon and the Team Magma climax. Sapphire gets Kyogre and the Team Aqua climax. The route, Cave of Origin structure, Wallace battle, and Rain Badge reward are shared.
