This guide is for players who already own Caleb: Summer Surge. It explains the Stellactrum system, how to read the card's Talent and stats, the full upgrade and Awakening path, and how to build the card for battle, Caleb Orbit, and Protocore matching.
Already pulled [Caleb: Summer Surge] and want to build it properly? If you need Diamonds for packs, stamina refreshes, or event resources, you can use the Love and Deepspace top-up page on Topuplist through the official Topuplist store, then follow this guide to invest in the Memory efficiently.
How to Read Caleb: Summer Surge
A 5-Star Memory in Love and Deepspace is more than a collectible. It has combat value through its Slot Type, Stellactrum, Talent, base stats, Protocore slots, and upgrade path.
Before spending materials, open the Memory detail screen and confirm:
Field | What It Means | Why It Matters |
|---|---|---|
Slot Type | Solar or Lunar | Determines Protocore slot types |
Stellactrum | Emerald, Sapphire, Violet, Amber, Ruby, or Pearl | Determines color match and Protocore compatibility |
Talent | HP, ATK, or DEF-based buff | Guides your stat build |
Stats | HP, ATK, DEF, CRIT Rate, CRIT DMG | Shows the card’s scaling profile |
Rank | Duplicate upgrade level | Improves long-term power |
Do not assume Caleb: Summer Surge uses a specific Stellactrum until you check the in-game card. Caleb Memories exist across multiple colors, so the live Memory screen is the final source.
Solar vs Lunar Slot Type
Slot Type is the first build detail to check. According to the Love and Deepspace Wiki’s Memories page, each Memory is either Solar or Lunar.
Solar Memories use α and β Protocores. Lunar Memories use γ and δ Protocores. This matters because your best Protocore main stats change depending on the slot type.
Slot Type | Protocore Slots | Common Build Focus |
|---|---|---|
Solar | α / β | HP, Oath Recovery, Expedited Energy, Oath damage |
Lunar | γ / δ | ATK, CRIT Rate, CRIT DMG, DMG Boost to Weakened |
If Caleb: Summer Surge is Lunar, prioritize γ and δ Protocores. If it is Solar, build around α and β instead. Always confirm on the card screen before farming.
Stellactrum and Protocore Matching
Stellactrum is the Memory’s color system. The six Stellactrum colors are Emerald, Sapphire, Violet, Amber, Ruby, and Pearl.
Protocores must match the Memory’s Stellactrum to be equipped. If Caleb: Summer Surge is Ruby, you need Ruby Protocores. If it is Emerald, you need Emerald Protocores. The same rule applies to every color.
Core Hunt farming generally follows color rotations:
Core Hunt Area | Colors |
|---|---|
Fusion Area | Emerald and Ruby |
Dissociation Area | Sapphire and Pearl |
Disambiguation Area | Violet and Amber |
Check the in-game Core Hunt schedule before spending stamina, because rotation days may vary by server schedule or event updates.
Talent and Stat Priority
Every Memory has a Talent, usually tied to HP, ATK, or DEF. Love and Deepspace Talents often reward crossing a stat threshold, then increase DMG Boost to Weakened based on additional stat investment.
Build around the Talent shown on Caleb: Summer Surge:
If the Talent scales with HP, prioritize HP-focused Protocore stats.
If it scales with ATK, prioritize ATK and damage stats.
If it scales with DEF, prioritize DEF-based stats.
For general damage, CRIT Rate, CRIT DMG, and DMG Boost to Weakened remain valuable.
The best build is not “Emerald by default” or “HP by default.” The correct build is whatever matches the card’s actual Stellactrum and Talent.
Upgrade, Ascension and Awakening Path
Building a 5-Star Memory has four major steps:
Level the Memory with Bottles of Wishes.
Ascend it with matching Stellactrum Crystals and Gold.
Equip matching Protocores.
Awaken it at max level with Awakening Heart: SSR and required materials.
Ascension materials must match the Memory color. For example, a Ruby Memory uses Ruby Crystals, while an Emerald Memory uses Emerald Crystals. Do not farm Emerald Crystals just because the card is Caleb; farm the color shown on the Memory.
Memory upgrades also return milestone rewards such as Diamonds or Empyrean Wish items on many 5-Star Memories, so claim Memory Rewards as you level and ascend.
Best Protocore Strategy
Your Protocore plan depends on Slot Type.
For a Lunar Caleb: Summer Surge, focus on γ and δ Protocores. γ commonly provides fixed ATK, while δ is where you look for strong offensive main stats such as CRIT Rate, CRIT DMG, or DMG Boost to Weakened.
For a Solar Caleb: Summer Surge, focus on α and β Protocores. α commonly supports HP, while β can support combat flow through Oath Recovery, Expedited Energy, or other build-specific stats.
General Protocore priorities:
Match the Memory’s Stellactrum.
Use higher-rarity Protocores when possible.
Prioritize the Talent’s scaling stat.
Add CRIT and DMG Boost to Weakened for damage.
Avoid over-upgrading weak temporary cores.
Are Duplicates Worth It?
Duplicate copies of a 5-Star Memory can be used for ranking up. Ranking improves the Memory’s long-term power and may strengthen its combat value.
However, limited Memory duplicates are expensive. If you only want a usable Caleb: Summer Surge, one copy plus proper leveling and Protocores is enough for most players. Chase duplicates only if Caleb is one of your main teams or you are intentionally building a high-investment limited card.
Since Caleb: Summer Surge is limited, future duplicate access depends on official reruns or return routes. Do not assume it will enter Xspace Echo.
Where to Use Caleb: Summer Surge
Once built, Caleb: Summer Surge is best used wherever its Stellactrum and stats match the stage requirements.
Good use cases include:
Caleb-focused teams
Deepspace Trial stages, especially Gravity-related content
Hunter Contest stages where the card matches Stellactrum needs
Stages where the Talent’s stat scaling helps break shields or improve weakened damage
The Love and Deepspace Wiki notes that matching a battle’s Stellactrum requirements helps break Wanderer shields more efficiently. That is why color matching matters as much as raw card rarity.
If you are short on Diamonds for upgrade packs or stamina-related purchases, the Love and Deepspace top-up page on Topuplist can help you prepare resources through the official Topuplist store.
Build Priority Checklist
Use this order after pulling Caleb: Summer Surge:
Confirm Slot Type.
Confirm Stellactrum.
Read the Talent.
Farm matching Protocores.
Level the Memory.
Ascend with matching crystals and Gold.
Equip Protocores that support the Talent.
Test it in Deepspace Trial and Hunter Contest.
Awaken only if you plan long-term use.
Rank up only if duplicates fit your budget.
The safest rule is simple: verify the card first, farm second. Most build mistakes come from assuming the color or Talent before checking the actual Memory screen.
Final Recommendation
Caleb: Summer Surge is worth building if you already pulled it, especially if Caleb is one of your main love interests or you need stronger Memories for his combat teams. But the correct build depends on the card’s actual Slot Type, Stellactrum, and Talent.
Do not blindly farm Emerald materials or HP Protocores unless the card confirms that direction. Match its color, support its Talent, and invest in Protocores before committing rare Awakening materials.
For players accelerating upgrades during the event window, use the Love and Deepspace top-up page on Topuplist through Topuplist only after checking what you actually need in-game.
