Power in Hallownest comes from four tracks: movement, Nail, spells, and survivability. Spend on them in the right order.
Most Hollow Knight walls are not skill walls, they are power walls. A boss feels impossible mostly because your Nail, masks, or spells are a tier behind where they should be.
Progression runs on four parallel tracks: movement abilities that open the map, Nail upgrades that raise damage, spell upgrades that add burst, and survivability from masks and Soul vessels. Knowing which to chase next is the whole game plan.
The wiki confirms the Nail upgrades four times and each spell has a stronger second form. Stack those with extra health and a few key charms and the difficulty curve flattens out fast.
This guide sets a clear upgrade order: what to grab early, what to save Geo and Pale Ore for, and the survivability picks that matter more than raw damage.
Mask Shards and the early Nail upgrades for survivability and damage.
Grab every ability on sight, they unlock everything else.
Upgrade Vengeful Spirit to Shade Soul as soon as you can.
Save Pale Ore for the Pure Nail before deep optional bosses.Every point of power in Hollow Knight comes from one of four tracks, and they are spent with different currencies. Balancing them is what keeps you ahead of the difficulty curve.
| Track | Currency | Payoff |
|---|---|---|
| Movement | Found, not bought | Opens new areas and bosses |
| Nail | Geo plus Pale Ore | Higher melee damage |
| Spells | Story progress | Ranged burst damage |
| Survivability | Geo and exploration | More health and Soul |
Per the wiki, movement abilities are mandatory and gate the world, so they take care of their own order. The choices that matter are how you spend Geo, Pale Ore, and charm notches across the other three.
Early on, prioritize survivability over damage. In actual play, two extra masks and a Soul upgrade carry harder boss fights than a single Nail tier does.
Grab every movement ability the moment it is available, with no exceptions. They are free, they are mandatory, and each one unlocks huge chunks of the map.
The core six are the Mothwing Cloak dash, the 
Mantis Claw wall cling, the Crystal Heart super dash, 
Monarch Wings double jump, the Shade Cloak shadow dash, and the 
Dream Nail.
The full pickup route is covered in our walkthrough. For progression the rule is simply that movement always comes before optional upgrades, since it decides what you can even reach.
The Nailsmith in the City of Tears upgrades your Nail four times for Geo and Pale Ore, and each tier is a flat damage jump. Per the wiki, there are six Pale Ore in the game, exactly enough for the full Pure Nail.
| Nail | Damage | Cost |
|---|---|---|
| Old Nail | 5 | Starting weapon |
| Sharpened Nail | 9 | 250 Geo |
| Channelled Nail | 13 | 800 Geo + 1 Pale Ore |
| Coiled Nail | 17 | 2000 Geo + 2 Pale Ore |
| Pure Nail | 21 | 4000 Geo + 3 Pale Ore |
The first two upgrades are cheap and worth rushing. The wiki notes Pale Ore is the real bottleneck, scattered in hard-to-reach spots, so plan the last two tiers around collecting it.
Hollow Knight has three spells, and each has a stronger second form. Spells cost Soul, so they pair naturally with the Soul survivability track.
| Base spell | Upgrade | Use |
|---|---|---|
 Vengeful Spirit | Shade Soul | Horizontal ranged damage |
 Desolate Dive | Descending Dark | Down-slam, breaks floors |
 Howling Wraiths |  Abyss Shriek | Upward and area damage |
According to the wiki, the Shade Soul upgrade roughly doubles Vengeful Spirit's damage, which makes it the highest-value spell upgrade in the game. Get it as soon as the Soul Sanctum opens.
Survivability is the track most new players underrate. More health and more Soul mean more mistakes survived and more healing per fight.
Per the wiki, Mask Shards come in groups of four, and four shards make one extra mask of health. With all 16 shards you go from five masks to nine.
The wiki specifies 
Vessel Fragments work the same way: three fragments add one Soul vessel, and all nine give you the Soul to cast and heal more often. Both are spread across the map and through vendors.
Here is a clean priority list that keeps you ahead of the bosses without backtracking for upgrades you skipped. Treat it as a default, not a rule.
Quick Slash and a strength charm transform your damage.The wiki notes charms can swing damage hard: a strength charm adds 50% and Quick Slash adds 32% attack speed. Our best charms guide ranks which to slot first.
Progression pulls from the Nail, spells, charms, and Geo income. These guides go deeper on each track.
