Both previews start at +0. The +3 price is cumulative and does not reveal the separate +2 or +3 step costs.

Sample boundary: do not convert these two observations into a universal percentage, shard-cost curve, or per-rank formula.
What is known
Progression rules
Dropped weapons have levels. Higher levels deal more ink damage, but the exact curve still needs controlled tests.
Standard manual enhancement reaches +5. This is distinct from weapon level and rarity.
Spirhalite Crystals are required after a sufficiently high enhancement level.
After clearing the story, Weapon Powers on 5-star weapons can be replaced and strengthened with fragments.
Before you spend
Use this checklist
- 1
Confirm the exact copy. Name, level, rarity, current + rank, and attached powers all matter.
- 2
Preview the final rank. The UI lets you compare the resulting stats and total material need.
- 3
Preserve unique powers. Do not scrap a rare roll just because a higher-level normal copy appears.
- 4
Capture the result. Screenshots make future comparisons reproducible across game versions.
FAQ
Weapon upgrade questions
What is the standard weapon upgrade cap in Splatoon Raiders?
Ordinary weapons can be manually enhanced to +5. Five-star weapons can continue beyond +5.
Where do you upgrade weapons?
Use Frye’s Weapon Stash on the Hideout Ship after the facility is unlocked.
Can I use the Steam Blaster sample as a universal cost formula?
