There is one ability in Project Slayers 2 that never shows up in the skill tree no matter how many points you dump into it. It is the N skill, the explosive lightning move players have been calling the secret running skill, and it is gated behind a progression bar rather than an unlock node. The path to it runs through a vendor selling gourds at a shrine most players walk straight past.
Quick answer: Max your Slayer Progress to Lv 4 by buying Large Gourds from Ren at Butterfly Estate. Each costs 8,800 Wen, and maxing out runs roughly 260,000 Wen total.
What the N skill is and why the skill tree does not have it
The N skill is a separate ability tied to your Slayer Progress level, not to skill points. Spending points normally will never reveal it, which is why so many players assume it is a clan-exclusive move or a bug. In the footage it fires as a lightning burst while the character is in Sleepless Knight Mode with Kel Agatsuma’s Slayer Progress sitting at Lv 4 (Max).
Because the requirement is a maxed bar, there is no shortcut, no hidden NPC, and no quest chain. You raise Slayer Progress until it reads Lv 4 (Max), and the skill becomes available.
Requirements and total Wen cost
| Detail | Value |
|---|---|
| Requirement | Slayer Progress Lv 4 (Max) |
| Vendor | Ren, at the red gourds |
| Location | Butterfly Estate shrine |
| Item | Large Gourd |
| Price per gourd | 8,800 Wen |
| Approximate total | ~260,000 Wen |
That total is the realistic number to plan around. Gourds are bought one at a time, so the grind is a currency grind rather than a combat one, and there is no discount for buying in bulk.
Bank your Wen before you head to the shrine. Repeated trips back and forth are the main time sink here, not the purchase itself.
How to max Slayer Progress at Butterfly Estate
How to confirm the skill unlocked
Go back into the menu and reopen Player Info. When the entry reads Slayer Progress Lv 4 (Max), you have hit the cap and there is nothing further to buy from Ren for this purpose.
From there, the N skill is usable in-game. Pressing N triggers the lightning ability rather than doing nothing, which is the clearest sign the unlock went through. If the bar still shows a lower level, you have more gourds to buy and more Wen to earn.
The whole process is less about finding something hidden and more about committing the currency. Roughly 260,000 Wen is a serious chunk of change for most players, but it is a one-time cost for an ability the skill tree simply will not hand you.
