Complete guide to obtaining and evolving Riolu into Lucario in Pokemon BDSP with advanced strategies and optimization tips
Prerequisites and Preparation: What You Need Before Starting
Before embarking on your quest for Riolu, ensure you’ve met these critical prerequisites that many trainers overlook.
Pokemon Brilliant Diamond & Shining Pearl maintain the original Sinnoh region’s progression gates, meaning certain Pokemon remain inaccessible until specific story milestones. Riolu falls into this category, requiring more preparation than most team additions.
Many trainers attempt this journey prematurely, wasting hours navigating to inaccessible areas. Here’s what you absolutely need before starting:
Pro Tip: Before heading to Iron Island, stock up on healing items and Repels. The cave contains level 30-36 Pokemon that can waste your resources if you’re not prepared.
Journey to Iron Island: Step-by-Step Navigation Guide
Navigating to Iron Island involves precise route planning that many trainers find confusing on their first attempt.
The journey from Pastoria City to Iron Island represents one of BDSP’s more complex navigation sequences. Follow this optimized path to minimize backtracking:
The sailor NPC is easily missed—he stands near the city’s bottom-left corner, partially obscured by dock structures. He won’t offer dialogue options until you’ve defeated Crasher Wake, a common point of confusion.
Navigation Shortcut: If you’ve already visited Canalave City previously, use the Fly HM directly there to skip the water navigation entirely. This saves 10-15 minutes of travel time.
Common Mistake: Many trainers waste time searching Iron Island for wild Riolu encounters. Remember: Riolu is ONLY available as an Egg from NPC Riley. Don’t bother encountering wild Pokemon in the caves.
Obtaining the Riolu Egg: The Riley Encounter
The Riley encounter on Iron Island represents a unique dual-battle sequence that rewards strategic team composition.
Once you disembark at Iron Island, proceed directly into the cave entrance. The interior follows a linear path with two levels—Riley awaits on the second level after approximately 3-4 minutes of exploration.
When you encounter Riley, he’ll immediately request assistance battling Team Galactic Grunts. This initiates a series of 2-3 mandatory dual battles with the following characteristics:
After defeating all Galactic Grunts, Riley will express gratitude and gift you the Riolu Egg. This Egg occupies a party slot immediately—you cannot store it in your PC until hatched.
Advanced Tactic: Before talking to Riley, save your game. If the Egg’s nature or IVs are unsatisfactory after hatching, you can soft reset (L+R+Start+Select) to reroll the Egg’s attributes.
Egg Hatching Optimization: Fastest Methods Revealed
Egg hatching in BDSP follows specific mechanics that can be optimized to reduce hatching time by 40% or more.
The Riolu Egg requires approximately 5,120 steps to hatch—among the longer hatch cycles in Sinnoh. Understanding step mechanics is crucial for efficiency.
Optimal Hatching Locations:
Speed Optimization Techniques:
Common Hatching Mistakes: Many trainers forget that Eggs don’t gain steps while menu navigation occurs. Don’t check your Egg’s status repeatedly—each menu open pauses step accumulation. Also, entering buildings resets your biking momentum, adding unnecessary time.
Friendship Evolution Mastery: Evolving Riolu into Lucario
Evolving Riolu into Lucario requires mastering two independent mechanics: friendship accumulation AND time-of-day restrictions.
This dual-requirement evolution confuses many trainers who max friendship but can’t trigger evolution. Here’s the complete breakdown:
Friendship Mechanics Explained:
Time-of-Day Critical Window:
Even with max friendship, Riolu ONLY evolves when leveled up during daytime hours (10:00 AM to 7:59 PM). The game uses your Nintendo Switch system clock, not in-game time.
Pro Evolution Tip: If you accidentally level Riolu at night with max friendship, don’t panic. The friendship persists—just wait for daytime and gain one more level (even from 100 to 100 via rare candy works).
Advanced Strategies: Maximizing Lucario’s Potential
Once evolved, Lucario becomes one of Sinnoh’s most versatile fighters—but proper training separates average from exceptional Lucarios.
Lucario’s Fighting/Steel typing and balanced stats allow multiple competitive builds. Here’s how to maximize your newly evolved Pokemon:
Optimal Move Set Development:
EV Training Guidance:
For balanced playthroughs, invest EVs in Attack and Speed. For competitive builds, consider Special Attack investment to utilize Aura Sphere’s perfect accuracy.
Item Synergies: Lucario benefits tremendously from items like Muscle Band (physical builds), Wise Glasses (special builds), or Life Orb (mixed offensive). Its Steel typing also makes it an excellent holder of Berries that weaken Fire, Ground, or Fighting attacks.
Final Pro Tip: If you plan to use Lucario competitively, consider breeding for optimal nature (Jolly or Adamant for physical, Timid or Modest for special) before your initial Riolu acquisition. The Egg soft-reset method mentioned earlier allows nature targeting without extensive breeding chains.
