Friendship, known as happiness in earlier games, plays a crucial role in Pokémon Brilliant Diamond and Shining Pearl (BDSP). This mechanic strengthens the bond between trainers and their Pokémon, enabling special evolutions and enhancing gameplay. Understanding how to monitor and increase friendship levels is key to progressing through Sinnoh’s challenges.
Understanding the Friendship System
The friendship system measures how much a Pokémon trusts and likes its trainer. High friendship unlocks evolutions for species like Eevee into Espeon or Umbreon, and affects battle performance indirectly through past mechanics like Return, though BDSP focuses primarily on evolutions. Unlike numerical values in modern titles, BDSP uses visual hearts via the Pokétch app for feedback.
Friendship starts low for captured wild Pokémon and builds through positive interactions. Maximum friendship, shown by two large hearts, typically requires around 160-220 points internally, a threshold lower than older games. Negative actions like fainting in tough battles can decrease it, emphasizing careful team management.
Acquiring the Essential Friendship Checker Tool
To track friendship, trainers need the Friendship Checker app for their Pokétch, a wrist-mounted device offering various utilities. First, obtain the Pokétch itself in Jubilife City by collecting three coupons from clowns scattered around town. Return them to the inventor for the device.
Next, progress to Eterna City after the Oreburgh Gym. Located northwest via Route 205 and Eterna Forest, enter the Pokémon Center. Speak to the woman in pink near the counter; she’ll examine your lead Pokémon and install the app. This tool becomes available early, aiding evolution planning.
- Step 1: Get Pokétch in Jubilife City (clown coupons).
- Step 2: Reach Eterna City Pokémon Center.
- Step 3: Talk to pink-dressed woman for app.
How to Access and Read Friendship Levels
Activate the Pokétch by pressing R on your Nintendo Switch controller. Cycle apps using the right-side button until reaching the Friendship Checker, where Pokémon float idly. Select a Pokémon by tapping (handheld) or using the left stick and A button.
Hearts emerge from the Pokémon: zero hearts indicate low friendship, one small heart moderate, two small hearts good, one large heart high, and two large hearts maximum. Hold A for full display; quick taps may only show jumping animations. Regular checks prevent over-investing in maxed Pokémon.
| Hearts Display | Friendship Level | Approx. Internal Value |
|---|---|---|
| 0 Hearts | Very Low | 0-99 |
| 1 Small Heart | Low | 100-159 |
| 2 Small Hearts | Moderate | 160-199 |
| 1 Large Heart | High | 200-219 |
| 2 Large Hearts | Maximum | 220+ |
Proven Methods to Boost Friendship
Increasing friendship demands consistent effort. Place the target Pokémon first in your party and equip a Soothe Bell, which amplifies gains. Walk 128 steps for a 50% chance of +1 friendship, doubled if following behind.
Battle victories, especially against Gym Leaders (+3 to +5 based on current level), level-ups without Rare Candies (+1 to +3), and daily massages in Veilstone City (+3) are efficient. Feed Poffins (+1) or EV-reducing berries like Pomeg (+1 to +10). Avoid bitter items like Energy Powder (-5 to -10).
- Daily Routine: Walk with Soothe Bell, massage in Veilstone.
- Battle Smart: Win without fainting; heal promptly.
- Items: Soothe Bell, berries, vitamins (cautiously).
Friendship Evolution Requirements
Several Sinnoh Pokémon evolve via high friendship plus conditions. Eevee needs day (Espeon) or night (Umbreon) at max friendship. Others like Golbat (Crobat), Chansey (Blissey), and Riolu (Lucario) require only high friendship and level-up.
| Base Pokémon | Evolution | Conditions |
|---|---|---|
| Eevee | Espeon | High friendship + Daytime level-up |
| Eevee | Umbreon | High friendship + Nighttime level-up |
| Eevee | Leafeon | Moss Rock (no friendship needed) |
| Riolu | Lucario | High friendship + Level-up (happiness daytime irrelevant) |
| Golbat | Crobat | High friendship + Level-up |
| Chansey | Blissey | High friendship + Level-up |
Note: BDSP retains classic rules; no affection separation like Sword/Shield.
Advanced Tips and Common Pitfalls
Maximize efficiency by prioritizing one Pokémon at a time in the lead slot. Following Pokémon gain extra walking bonuses. Track progress weekly to hit evolution thresholds timely. Pitfalls include using Rare Candies (no gain) or letting high-level foes faint your team (-10 at max friendship).
Veilstone’s masseuse offers daily +3; later Resort Area provides bigger boosts. For stubborn cases, chain battles in tall grass or use Exp. Share for safe level-ups.
Alternative Checking Methods
Before the app, visit Hearthome City’s Trainer Fan Club. The top-left woman comments on your lead Pokémon’s feelings, hinting at friendship. This persists post-app for verification.
