Item descriptions never say this; the game shows it in the **Restoration time** line of the stone and skill tooltips. (Verified) - **Buff (self)** (30 stones): **+60 s** ×5, **+3 min** ×10, **+10 min** ×15 - **Buff (self + party)** (20 stones): **+60 s** ×10, **+3 min** ×5, **+10 min** ×5 - **Attack** (55 stones): **−5 s** ×1, **−4 s** ×1, **−3 s** ×1, **−2 s** ×1, **−1 s** ×1, **+21 s** ×5, **+30 s** ×10, **+35 s** ×10, **+40 s** ×5, **+45 s** ×5, **+60 s** ×10, **+62 s** ×5 The only family that shortens the cooldown: [Cooldown reduction](https://karos-wiki.pages.dev/en/ssfam-6311) (**−1 s** … **−5 s**). How the stone's **Duration** value is applied (only to the stone's extra effect, or to the whole buff) is unknown. The skill tooltip shows this duration instead of the skill's own. (Unknown) **Status badges** - (Verified) This information is verified. - (Estimate) Estimate: likely, but not confirmed. - (Unknown) Not known yet; can be measured by testing in game. ## How it works 1. Talk to a Mentor (Instructor) NPC (table below) and open **Super Skill option** in the menu. 2. Drag the super skill into the **Super** slot and the stone into the **Super Skill Stone** slot. 3. The button depends on the state: add if the skill has no stone; remove if the skill already has a stone or the same stone is dragged; change if a different stone is dragged. The fee is paid in karats. ### Mentor NPCs 5 | NPC | Maps | | --- | --- | | [Kilias](https://karos-wiki.pages.dev/en/npc-9300111) | [Berneo](https://karos-wiki.pages.dev/en/map-19003) | | [Varn](https://karos-wiki.pages.dev/en/npc-9400101) | [Tempteroon](https://karos-wiki.pages.dev/en/map-19004) | | [Ugerst](https://karos-wiki.pages.dev/en/npc-9500111) | [Peltrock](https://karos-wiki.pages.dev/en/map-19005) | | [Loelknym](https://karos-wiki.pages.dev/en/npc-9850012) | [Heristum](https://karos-wiki.pages.dev/en/map-19010) | | [Prodius](https://karos-wiki.pages.dev/en/npc-9850112) | [Zastava](https://karos-wiki.pages.dev/en/map-19014) | ### Fees | Action | Fee | Status | | --- | --- | --- | | Add | 10,000 Karat | (Verified) | | Delete option | 10,000 Karat | (Verified) | | Change option | 20,000 Karat | (Verified) | ### Rules - Each super skill has a single stone slot. Passive stones go on the passive super skills (Lv.10/45), active stones on the active ones (Lv.25/40/60/75). (Verified) - A removed or replaced stone most likely returns to your inventory; the action is refused when the inventory is full. Make room first. (Estimate) - A super skill cannot be changed while a stone is applied to it. Remove the stone first (10,000 karat). (Verified) Related item: [Super Skill Change Coupon](https://karos-wiki.pages.dev/en/item-140024) (Estimate) ## Which stone fits which super skill Compatibility: passive stones fit 28 passive super skills; buff stones fit only the 16 'Support' super skills; attack stones fit 40 Damage/Debuff super skills. Mystic: no buff super skill, so buff stones cannot be used.

The stone's penalty is added to the skill's cooldown at the chosen level. "Stone effect" is the stone's own duration (5–10 s) divided by the cooldown. The "Advice" column is an interpretation derived from these numbers. Whether the stone's Duration replaces the buff's own duration is unknown; the table below uses the buff's own duration. (Unknown) Some buff stones show a 'Duration' in the tooltip: Magic protection 10 s, Physical protection 10 s, Deadly attack (attack +, defense -) 5 s, Acceleration (attack speed) 10 s, Iron wall (critical damage reduction) 10 s, Invulnerability (fixed damage, movement -) 5 s, Acceleration (movement speed) 10 s. The skill tooltip shows it instead of the skill's own duration; whether it applies only to the stone effect or to the whole buff is unknown. Test in game before using it on a long buff.
