Complete guide to locating, catching, and evolving Swablu into Altaria in Pokemon BDSP with advanced strategies
Understanding Swablu’s Origins and Availability
The beloved Normal/Flying-type Swablu originally debuted in Generation III’s Hoenn region, capturing trainers’ hearts with its cloud-like appearance and gentle nature. Many players who experienced Ruby and Sapphire on Game Boy Advance hold special nostalgia for this fluffy avian Pokemon and its majestic evolution, Altaria.
Fortunately for nostalgic trainers, both Swablu and its evolution Altaria have migrated to Sinnoh in the Brilliant Diamond & Shining Pearl remakes, offering new opportunities to add this dynamic duo to your team.
The 2021 Sinnoh reimagining brings numerous Hoenn region Pokemon into the mix, with Swablu standing out as a particularly sought-after addition due to its unique typing transition from Normal/Flying to Dragon/Flying upon evolution.

Essential Preparation for Swablu Hunting
Before embarking on your Swablu hunting expedition, ensure you’ve reached critical game progression milestones. The primary requirement involves unlocking the Grand Underground system, which becomes accessible after reaching Eterna City and completing specific story objectives.
Visit the Underground Man residing in the small house immediately east of Eterna City’s Pokemon Center to receive your essential Explorer Kit. This key item grants access to the vast underground network where Swablu resides. Many trainers make the common mistake of attempting to access the Grand Underground too early – you must have defeated the Eterna City Gym and obtained the Forest Badge to progress this storyline.
Essential Preparation Checklist:
- Reach Eterna City and defeat Gardenia’s Gym
- Obtain the Explorer Kit from Underground Man
- Stock up on Poke Balls (especially Quick Balls)
- Prepare Pokemon with False Swipe and status-inflicting moves
- Ensure you have Repels to avoid unnecessary encounters
Swablu Location Guide: Grand Underground Strategy
Activate your Explorer Kit from the Key Items menu to descend into the Grand Underground network. Experienced hunters recommend using entrance points near Eterna City or Jubilife City for optimal access to Swablu’s preferred habitats.
Advanced Spawn Strategy: Swablu’s appearance rates slightly increase during daytime hours in the Grand Underground. For maximum efficiency, combine time-based hunting with strategic resetting. Bring a Pokemon with the Compound Eyes ability at the front of your party (even if fainted) to boost the chance of Swablu holding a valuable item like a Pretty Wing.
Advanced Catching Techniques and Tips
Mastering Swablu capture requires understanding nuanced catching mechanics beyond simple ball throwing. While Quick Balls provide excellent initial capture probability at approximately 5x normal rate, their effectiveness diminishes after the first turn.
Ball Selection Hierarchy:
- Turn 1: Quick Ball (optimal choice)
- Subsequent Turns: Ultra Ball or Dusk Ball (in caves)
- Status Conditions: Timer Ball after 10 turns (4x capture rate)
Inflicting status conditions dramatically improves capture rates. Sleep and freeze provide the highest bonus (2.5x), while paralysis, poison, and burn offer 1.5x multipliers. Consider teaching a supporting Pokemon moves like Hypnosis, Thunder Wave, or Spore to facilitate easier captures.
Common Hunting Mistakes to Avoid:
- Using damaging moves that might knock out Swablu (it has modest defenses)
- Attempting capture without status conditions when Quick Ball fails
- Neglecting to check for held items that increase encounter value
- Wasting time in incorrect cave biomes – focus on the six specified locations
Team preparation should include a Pokemon with False Swipe to guarantee Swablu remains at 1 HP, combined with status-inflicting capabilities. This combination creates ideal catching circumstances for when Quick Balls inevitably fail on some encounters.
Evolving Swablu into Altaria
Unlike some Pokemon requiring special evolution items or trading, Altaria acquisition follows straightforward level-based evolution mechanics. Swablu transforms into the majestic Dragon/Flying-type Altaria upon reaching level 35, with no additional requirements or items necessary.
Critical clarification: Altaria does not spawn naturally in the wild within the Sinnoh region, making evolution the exclusive acquisition method. Attempting to find wild Altaria represents a common time-wasting misconception among trainers.
Upon evolution completion, Altaria automatically learns the powerful Dragon Pulse move, providing immediate STAB (Same-Type Attack Bonus) coverage. This 85-power Dragon-type special attack becomes a cornerstone of Altaria’s offensive capabilities.
The Pokemon Company / ILCAAltaria’s Dragon/Flying typing provides valuable resistances while maintaining offensive presence.
Post-Evolution Benefits: Beyond the impressive typing shift, Altaria gains significantly enhanced base stats including 70/90/105 defensive bulk and 80 special attack. Its Cloud Nine ability cancels weather effects in battle, providing strategic advantages against weather-reliant teams.
