Pokémon Diamond Version, Pearl Version, and Platinum Version - Friendship
Friendship is a measure of a particular Pokémon’s attachment to the player. Friendship ranges from 0 through 255.
When a Pokémon is created or traded from another player, it starts with its base friendship (normally 70 but depends on the species). A Pokémon hatched from an Egg starts with a friendship of 120 instead.
Here are the ways to raise or lower friendship.
| Method | Friendship 0-99 | 100-199 | 200-255 |
|---|---|---|---|
| Level Up | +5 | +3 | +2 |
| Protein, Iron, Calcium, Carbos, Zinc, HP Up, PP Up, PP Max | +5 | +3 | +2 |
| Pomeg/Kelpsy/Qualot/Tamato/Hondew/Grepa Berry | +10 | +5 | +2 |
| Begin a battle against a Gym Leader, Elite Four, or the Champion with the Pokémon in party (even if it doesn’t participate or the battle ended in defeat) | +3 | +3 | +1 |
| Every 128 steps, if the Pokémon is in party (50% chance) | +1 | +1 | +1 |
| X Attack, X Defend, X Speed, X Special, X Accuracy, Guard Spec., Dire Hit (but not X Sp. Def) | +1 | +1 | +0 |
| Daisy’s Fur Grooming (in Pallet Town; 3:00 PM hour only) | +10 | +10 | +10 |
| Heal Powder, Energy Powder | -5 | -5 | -10 |
| Energy Root | -10 | -10 | -15 |
| Revival Herb | -15 | -15 | -20 |
| Pokémon faints | -1 | -1 | -1 |
| Pokémon survived poisoning outside of battle | -5 | -5 | -5 |
| Poffin | +1 | +1 | +1 |
| Massage (Veilstone City) | +3 | +3 | +3 |
| Massage (Ribbon Syndicate, 2/3 chance) | +5 | +5 | +5 |
| Massage (Ribbon Syndicate, 1/3 chance) | +10 | +10 | +10 |
The friendship loss from Energy Root, EnergyPowder, Heal Powder, and Revival Herb doesn’t change depending on the Pokémon’s nature, even though these items are described as having a bitter taste. For example, the Pokémon doesn’t lose more friendship if it dislikes bitter foods or lose less friendship if it likes bitter foods.
If the Pokémon is holding a Soothe Bell, each friendship gain is multiplied by 1.5. Then, if the Pokémon was caught in a Luxury Ball, each friendship gain rises by 1. (Friendship doesn’t increase further even if it was gained in the place where the Pokémon was caught.)
A Pokémon that evolves through friendship will do so the next time it levels up and its friendship is 220 or more (after the battle ends, if any, and after adding friendship gain from leveling up).
Blast Burn, Draco Meteor, Frenzy Plant, and Hydro Cannon can be taught by a Move Tutor only if the Pokémon has a friendship of 255.
Friendship can be approximated by talking to the lady in the northwest corner of the Pokémon Fan Club in Hearthome City:
- 0: "Oh, my... I think this one really hasn’t taken too kindly to you."
- 1-49: "Hmm... It seems to dislike you a little."
- 50-99: "It’s feeling neutral toward you. It’s up to you to change that."
- 100-149: "It’s warming up to you. That’s my impression."
- 150-199: "It’s quite friendly to you. It must be happy being with you."
- 200-254: "It’s very friendly toward you. I can tell you treat it kindly."
- 255: "It simply adores you! Why, I feel like I’m intruding!"
Or by visiting the woman in the house on east-central Goldenrod City:
- 0-49: "It doesn’t seem to like you at all. It looks mean."
- 50-99: "You should treat it better. It’s not used to you."
- 100-149: "It’s quite cute."
- 150-199: "It’s friendly toward you. It looks sort of happy."
- 200-249: "I get the feeling that it really trusts you."
- 250-255: "It looks really happy! It must love you a lot."
Alternatively, open the Pokétch’s Friendship Checker (app no. 6) and tap and hold the Pokémon:
- 0-149 - Nothing
- 150-199 - One heart over the Pokémon
- 200-254 - Two hearts over the Pokémon
- 255 - Two big hearts over the Pokémon
To get the Friendship Checker, talk to the woman inside Eterna City’s Pokémon Center, near the entrance. This same woman will say:
- 0-69: "Hmm... It needs to get used to you more."
- 70-119: "It’s becoming comfortable around you, I think."
- 120-255: "It seems to like you. It must be happy being with you."
