The 10 upgrade types
All 146 upgrades in the upgrade database split into these types. The counts show where the depth is — and where the trap of “more must be better” lives:
| Type | Count | What it does |
|---|---|---|
| Damage | 33 | Flat and scaling damage boosts |
| Health | 24 | Max HP, healing, survivability |
| Elemental | 24 | Arcane, fire and on-hit procs |
| Skill | 18 | Ability, ammo and utility perks |
| Luck | 15 | Chance-based procs and crit-style rolls |
| Economy | 11 | Crystals, gold and drops |
| Speed | 9 | Movement, dash and airborne bonuses |
| Critical | 6 | Crit chance and crit damage |
| Greed | 5 | Greed-mode-specific perks |
| Weapon Mod | 1 | Direct weapon modification |
Damage is the deepest pool at 33, but that also means it is the most diluted — not every Damage perk fits your gun. Elemental (24) and Luck (15) are where the on-hit procs live, and those are what make a high fire-rate gun snowball.
The 5 rarity tiers in the data
| Rarity | Count |
|---|---|
| Common | 56 |
| Epic | 46 |
| Rare | 21 |
| Legendary | 18 |
| Greed | 5 |
The wiki’s Rarities overview names four rarities (Common, Epic, Legendary, Greed) but leaves its counts blank; the site’s own 146-entry dataset resolves to five buckets, with Rare as a real tier of 21 items.
Common is the largest tier (56) and the most overlooked — it holds workhorses like Autoloader. Rarity is availability, not power: a Common perk that feeds your core loop beats a Legendary tuned for a build you are not running. When two upgrades look equal, the one that triggers more often wins.
Perk versus weapon mod
Only one upgrade is a true Weapon Mod; everything else is a perk layered on your character. Both appear under “Upgrades” in the wiki, so the database’s type filter is the only clean way to tell them apart. Build with perks for your character, and treat the single weapon mod as a specialist pick.
