The Sparks of Galaxy event is one of the main ways to obtain rare Immortal fragments and Artifact fragments for Shadow and Holy immortals. It’s structured like a gacha draw with pity, meaning you spend draws on a prize pool that includes Immortal fragments, Artifact fragments, Dragon Essences, and Dragon Crystals. There is also a pity system, which guarantees Immortal fragment drops if you go too long without one (100 draws).

This guide covers the event mechanics, drop rates, pricing breakdowns, and practical plans for targeting both Immortal and Artifact fragments efficiently.

Event Mechanics

• Each draw has a chance to give a reward from the pool:
  • Immortal Fragments (10x): 4 slots at 1.30% each → 5.2% total chance
  • Artifact Fragments (5x): 3 slots at 1.20% each → 3.6% total chance
  • Dragon Essence (1x): 2 slots at 17% each → 34% total chance
  • Dragon Crystal Chests (10x): 28% chance
• Pity rule: If you go 100 pulls without an Immortal fragment, the next pull is guaranteed to give one (10 frags). Pity resets after each Immortal fragment drop.
• No pity for Artifact fragments.
• Rewards are selection chests for Shadow/Holy Immortals or Artifacts, so duplicates aren’t a risk.

Drop Math & Expectations

Immortal Fragments

• We get 10x Immortal frags per hit.
• Chance per pull = 5.2%.
• To reach 60 frags (6 hits):
  • Expected pulls: ~115
  • Median: ~109 pulls
  • 95% certainty: ~197 pulls
• Thanks to pity, bad luck is capped, but given the decent drop rate we are not going to run into pity very often. That being said, it will happen and it does reduce the average expected a bit.

Artifact Fragments

• Need 5x Artifact frags per hit.
• Chance per pull = 3.6%.
• To reach 60 frags (12 hits):
  • Expected pulls: ~333
  • Median: ~324 pulls
  • 95% certainty: ~500 pulls
• No pity = much wider variance.
• Artifact frags are harder to obtain than immortal fragments, which is standard in these events. Given you need 4750 immortal fragments to max out an immortal and only 900 artifact fragments (assuming good craft roll within the standard 15 to max) it is not as bad as it looks initially. But you are on average getting the 15 artifacts = 1 max in 4995 pulls on average whereas you need 9104 draws to get the total 4750 immortal fragments needed for a max + talents.

Pricing Breakdown

You can buy pulls through cash packs or with gems.

Pack Options (per event stock)

• $1 → 5 pulls ×12 = 60 pulls → $12 total → $0.20/pull
• $2 → 10 pulls ×10 = 100 pulls → $20 total → $0.20/pull
• $5 → 18 pulls ×8 = 144 pulls → $40 total → $0.2778/pull
• $10 → 24 pulls ×6 = 144 pulls → $60 total → $0.4167/pull
• $15 → 32 pulls ×5 = 160 pulls → $75 total → $0.4688/pull
• $30 → 40 pulls ×2 = 80 pulls → $60 total → $0.75/pull
• $50 → 50 pulls ×1 = 50 pulls → $50 total → $1.00/pull
• All bundles combined: 738 pulls for $317 → $0.43/pull average

Strategies depending on your spending level, the more time you have the cheaper you can get it!

Three clean routes to farm ~1020 Immortal fragments from the draw event

Quick baseline:

• Immortal frags = 10 per hit, hit rate 5.2% per pull, with a 100-pull pity that forces an Immortal frag if you haven’t hit one yet.
• To reach ~1020 frags you need ~102 hits → expected ~1,962 pulls. Pity mostly just trims bad-luck streaks; the mean stays about the same over this many pulls.
• For these strategies or plans, we are going to be doing three different versions. In plan A we are using only the cheapest 1 and 2 dollar bundles. This will be most efficient (see below) but also take more time given the stock caps. In Plan B we are including the slighly less efficient but still very good value 5$ bundle and for Plan C we are going fast and getting the 10 and 15 dollar bundles too.
• Bundle reminder:
  • $1: 12× (5 pulls each) → 60 pulls total → $12 → $0.20/pull
  • $2: 10× (10 pulls each) → 100 pulls total → $20 → $0.20/pull
  • $5: 8× (18 pulls each) → 144 pulls total → $40 → $0.2778/pull
  • $10: 6× (24 pulls each) → 144 pulls total → $60 → $0.4167/pull
  • $15: 5× (32 pulls each) → 160 pulls total → $75 → $0.4688/pull

Plan A — Cheapest money (only $1 + $2 packs)

This is the budget grinder. You buy only the cheapest packs and accept more events.

• Pulls per event: 60 + 100 = 160 pulls for $32
• Target pulls: ~1,962
• 12 full events = 12 × 160 = 1,920 pulls → $384
• Remainder since we are a bit short on draws (unles you got lucky): 1,962 − 1,920 = 42 pulls needed –> Grab 4× $2 (40 pulls, $8) + 1× $1 (5 pulls, $1) → 45 pulls for $9.
• Total Plan A: ~1,965 pulls i.e. 1020 immortal fragments for a price of $393 over the course of ~13 events (12 full + a tiny top-up in the 13th)

This is the best $/pull you can get. It just takes the longest.

---

Plan B — Fewer events (add $5 packs)

Here you still keep things pretty efficient, but you finish way faster.

• Pulls per event: ($1+$2+$5) = 60 + 100 + 144 = 304 pulls for $72
• 6 full events = 6 × 304 = 1,824 pulls → $432
• Remainder: 1,962 − 1,824 = 138 pulls
  • Cheapest way to finish (still only using 1/2/5): 12× $1 (60 pulls, $12) + 8× $2 (80 pulls, $16) → 140 pulls for $28
• Total Plan B: ~1,964 pulls, i.e. 1020 immortal fragments for a price of $460 over the course of ~7 events (6 full + a small top-up)

This is the sweet spot if you value time without burning money on the worse-value packs.

---

Plan C — Fastest timeline (also buy $10 + $15)

Now we throw in the $10 and $15 bundles to compress the event count further.

• Pulls per event: ($1+$2+$5+$10+$15) = 60 + 100 + 144 + 144 + 160 = 608 pulls for $207
• 3 full events = 3 × 608 = 1,824 pulls → $621
• Remainder: 1,962 − 1,824 = 138 pulls
  • Cheapest top-up: 12× $1 (60, $12) + 8× $2 (80, $16) → 140 pulls for $28
• Total Plan C: ~1,964 pulls (1020 immortal frags) for the price of $649 so quite expensive, but done in just ~4 events (3 full + a small top-up)

You’re paying for speed here. It’s noticeably more expensive than Plan B, but you’re done in roughly half the events of Plan A.

Gems-only comparison

Pricing of rewards, as you can expect if you are using only Gems

• 5 pulls = 1000 gems → 200 gems per pull
• 115 pulls (60 Imm frags) ≈ 23,000 gems
• 334 pulls (60 Art frags) ≈ 67,000 gems
• 1020 immortal fragments for comparison, i.e. ~1,965 pulls → ~393,000 gems

---

What I’d do (player perspective)

• If you’re patient and care about value: Plan A. It’s the cheapest by far (~$393) but you’re in for ~13 events.
• If you want a good balance: Plan B. This is my preferred route: ~$460 and ~7 events.
• If you just want it done fast: Plan C. You’ll likely wrap in ~4 events for ~$649.

Small tip: because pity triggers every 100 “no-hit” pulls, over a 2k-pull grind the variance is low. You don’t need a huge extra buffer—just don’t cut it to the exact pull on your last event (buy +20–40 extra pulls if you’re paranoid).

---

Conclusion

• Always buy the $1 and $2 packs — they’re the best value in the event.
• If you’re patient, Plan A (just $1 + $2) is the best long-term strategy.
• If you want speed, add $5 packs for a balanced Plan B. Only go to $10/$15 if you want to finish in very few events.
• Gemming this event is expensive — only use if you have excess saved.
• Don’t be afraid of the pity system — failing pulls aren’t wasted since pity forces progress.
• Over long grinds (like 1k+ frags), variance smooths out and your average pulls will line up close to the math.

Sparks of Galaxy is a high-value but expensive event, offering one of the few reliable paths to Shadow/Holy Immortal and Artifact fragments.
