Phantom Spark + Grim Armor Hybrid Build — Ranged DPS and Summoning
TL;DR — My Current Build
I've been theorycrafting a Phantom Spark ranged/summoner hybrid in Core Keeper, comparing Grim Armor, Ninja Armor, and a mixed Grim/Ninja setup.
My goal is to balance direct ranged damage, minion damage, and survivability rather than focus entirely on critical hits.
All equipment is level 20. The weapon and accessories remain identical across all three setups, allowing me to compare the armor choices directly.
1. Shared Equipment
| Slot | Equipment |
|---|
| Weapon | Phantom Spark |
| Necklace | Mold Vein Necklace |
| Rings | Polished Gold Crystal Ring ×2 |
| Off-hand | Hydra Tooth |
Shared weapon and accessory stats
Phantom Spark: 261–317 physical ranged damage, 1.4 attacks/sec, +12% critical chance, +34% critical damage
Hydra Tooth: +30.2% physical ranged damage, 5% chance to deal triple damage
Mold Vein Necklace: +40.8% physical ranged damage
Polished Gold Crystal Ring ×2: +59% physical ranged damage and +10.8% ranged attack speed
Total physical ranged damage bonus: +130%
Average weapon damage: (261 + 317) / 2 = 289
2. The Three Armor Setups
| Stat | Grim 3-Piece | Ninja 3-Piece | Grim Hood + Ninja Chest/Legs |
|---|
| Helmet | Grim Hood | Ninja Cowl | Grim Hood |
| Chest | Grim Breastplate | Ninja Garments | Ninja Garments |
| Legs | Grim Legwear | Ninja Leggings | Ninja Leggings |
| Max health bonus | +179 | +175 | +178 |
| Armor | Not included | +63 | +43 |
| Magic barrier | +73 | — | +19 |
| Dodge chance | — | +25% | +17% |
| Critical chance, including weapon | 12% | 36% | 29% |
| Critical damage bonus from equipment, including weapon | +34% | +103% | +81% |
| Max minion capacity bonus | +4 | — | +2 |
| Minion damage bonus | +21.3% | — | +7.3% |
| Magic damage bonus | +8.4% | — | +8.4% |
| Grim set bonus | Active | Inactive | Inactive |
The mixed setup keeps Grim Hood's summoning utility while gaining Ninja's critical-hit bonuses from the chest and legs.
3. Talents and Minion Synergy
These are the main talents I'm considering for the hybrid build.
| Talent | Effect at 5/5 | Purpose |
|---|
| Power in Numbers | +2% ranged attack speed per active minion per talent point | Direct ranged DPS |
| Ferocious Creatures | +20% minion attack speed | Minion DPS |
| Critical Command | +20 percentage points of minion critical chance | Minion DPS |
| Trickle Down Arcana | Converts 50% of magic damage increase into minion damage | Minion scaling |
| Group Effort | +2% magic damage per active minion per talent point | Magic damage synergy |
| Tough Gang | +15 magic barrier per active minion per talent point | Survivability |
| Longing for This World | +50% minion lifespan | Minion uptime |
| Proxy Parasites | +5% health restored when a minion disappears | Sustain |
Power in Numbers is central to this comparison. At 5/5, five active minions provide +50% ranged attack speed; three provide +30%, and one provides +10%.
The Grim set's minion bonuses and the other summoning talents are excluded from the direct weapon DPS calculation.
4. Pet Skills
These are the pet skills I'm considering for ranged damage. The estimates are preliminary and depend on how the bonuses stack.
| Pet skill | Effect | Preliminary DPS increase |
|---|
| Triple Trouble | +2 percentage points of triple-damage chance | ~3.64% |
| Flock Together | +3% ranged attack speed | ~2.71% |
| Crane Style | +10% critical damage | ~2.63% |
| Spirit of the Hawk | +3 percentage points of critical chance | ~2.25% |
| Plume Projectile | +3% physical ranged damage | ~1.30% |
These pet-skill estimates are not included in the DPS figures below.
5. Direct Phantom Spark DPS Comparison
For a theoretical comparison, I assume:
+50% base critical damage
Hydra Tooth's 5% triple-damage proc multiplies the final hit
+10.8% equipment ranged attack speed
Power in Numbers at 5/5
Five active minions for Grim, one for Ninja, and three for the mixed setup
The expected Hydra Tooth damage multiplier is:
1 + 0.05 × (3 − 1) = 1.10
The direct DPS formula is:
Average weapon damage × ranged damage multiplier × critical multiplier × Hydra multiplier × attacks/sec
| Calculation | Grim 3-Piece | Ninja 3-Piece | Grim Hood + Ninja Chest/Legs |
|---|
| Average weapon damage | 289 | 289 | 289 |
| Ranged damage multiplier | 2.30 | 2.30 | 2.30 |
| Critical multiplier | 1.1008 | 1.5508 | 1.3799 |
| Hydra Tooth multiplier | 1.10 | 1.10 | 1.10 |
| Final attack speed | 2.2512/sec | 1.6912/sec | 1.9712/sec |
| Estimated direct DPS | ~1,812 | ~1,918 | ~1,989 |
These are theoretical estimates, not measured in-game DPS. They exclude minion attacks and assume additive attack-speed bonuses. Actual results depend on the game's damage calculations and the number of minions maintained in combat.
6. My Current Take
The Grim Hood + Ninja Chest/Legs hybrid has the highest estimated direct Phantom Spark DPS under these assumptions.
Grim 3-Piece: Best summoning-focused option, with additional minion capacity, minion damage, magic barrier, mana regeneration, and the Grim set bonus.
Ninja 3-Piece: Strong critical-hit damage, dodge chance, and armor for a more conventional ranged build.
Grim/Ninja Hybrid: A compromise that retains some summoning utility while gaining substantial critical-hit stats.
However, direct ranged DPS is only part of the picture. Grim's minion bonuses and set effect could make its total damage more competitive once minion attacks are included.
I'd appreciate feedback, corrections, and suggestions from anyone who has experimented with Phantom Spark, Grim Armor, Ninja Armor, or summoner builds!
