Where to obtain it in Platinum

Check the location, method and conditions before travelling. A gift, trade, Honey Tree, daily replacement or stationary interaction is different from ordinary grass. Level ranges combine matching documented encounter slots.

These records are filtered to Platinum. Time, Poké Radar, swarm, GBA insertion, daily and story conditions remain separate. Postgame areas require their story access; no listed area is promised to be open on a fresh save.

Evolution family and Generation IV requirements

Friendship evolution uses the original threshold of 220. Held-item trades need a compatible second game and system. Platinum uses special rocks, Mt. Coronet magnetic evolutions, learned-move requirements and Beauty rather than later replacement methods.

Hidden Abilities did not exist in Generation IV. The table restores original ability slots where a species changed in later games; an ability’s modern behavior must not be assumed to match Platinum.

The Solaceon Town Day Care supports breeding before the League. Undiscovered species cannot produce Eggs. Some baby forms require the matching incense on a parent, while trade evolutions still need the trade rather than only a Day Care level.

Every row uses the Platinum version group. Level 1 moves include starting and reminder moves; a later caught specimen need not already know every entry. Evolution timing affects which stage learns a move. Pastoria’s Move Reminder charges a Heart Scale.

Platinum TMs are single-use: teaching one consumes that copy. HMs are reusable and require the Move Deleter to be forgotten. Defog is HM05 and Rock Climb is HM08; these are the Generation IV field moves, with their own badge requirements.

Egg moves and Platinum Move Tutors

Recorded Platinum Egg moves: Block, Defense Curl, Explosion, Flail, Rock Blast, Rock Slide, Rollout.

Recorded Platinum tutor compatibility: AncientPower, Earth Power, Iron Head, Mud Slap, Rollout, Snore, Twister.

Tutor compatibility does not mean every listed technique comes from the same shard tutor. Starter ultimate moves, Draco Meteor and other special services have their own requirements.

FIELD NOTE

Use Onix’s exact Platinum method and condition. Daily encounters, counterpart-game species, original evolution rules and external Egg requirements need separate collection plans.
