How to Get Reverse Cursed Technique in Sorcerer Ascent
You unlock Reverse Cursed Technique in Sorcerer Ascent by reaching Cursed Energy Control level 10, clearing the Shibuya Descent story mission, and then completing the “Negative Times Negative” trial offered by the Awakened Tutor in the Hidden Wards. Once all three prerequisites are satisfied, the skill appears in your Technique Menu under Support abilities and can be bound to any free hotkey. The technique costs 40 Cursed Energy to cast and is not a passive unlock, so it will not show up purely from levelling Cursed Energy Control — the trial must be completed first.
The three unlock prerequisites in detail
The unlock is gated behind three separate requirements that veteran players commonly confuse, because only the first one appears in the early tutorial tooltips. Meeting one or two of them will not trigger the technique, and the game gives no explicit error message telling you which step is missing.
1. Cursed Energy Control level 10
Cursed Energy Control is the blue-branch skill tree stat that governs how fast your energy regenerates and how efficiently techniques consume it. Per the game’s official patch notes for the 2.1 update, the requirement for the Reverse Cursed Technique trial is a flat level 10 in this stat, with no partial credit for level 9. In practice this takes roughly 14–18 hours of ordinary play if you route through the main story, or considerably longer if you spread points across the physical and domain branches instead.
Each point in Cursed Energy Control costs escalating skill shards:
- Levels 1–4: 1 shard each (4 total)
- Levels 5–7: 2 shards each (6 total)
- Levels 8–9: 3 shards each (6 total)
- Level 10: 5 shards (the final point, a deliberate spike)
That is 21 shards to reach level 10 from scratch. Shards drop from cursed spirit encounters at roughly a 1-in-4 rate on standard difficulty, so budget about 80–90 kills if you are farming deliberately rather than picking them up passively.
2. Clearing the Shibuya Descent story mission
Shibuya Descent is the mid-game story mission that unlocks around player level 24–27 depending on your route. Importantly, you must complete the mission, not merely reach it — the trial NPC will not spawn until the mission’s completion flag is set. The relevant flag is ShibuyaCleared, which the game sets automatically when you exit the final combat arena and return to the overworld map.
If you are replaying the mission for loot, note that a replay does not reset or re-set the flag; it stays set once earned. Per the developer’s official patch notes, the Reverse Cursed Technique unlock was moved from a pure level gate to a story-flag gate in update 1.9 specifically to stop players from rushing the technique before the mid-game story beats.
3. The “Negative Times Negative” trial
With those two conditions met, travel to the Hidden Wards district and find the Awakened Tutor, who stands near the broken torii gate on the eastern edge of the map. The tutor offers a single-instance trial called “Negative Times Negative.” The trial is a solo encounter against a single high-damage spirit that punishes you for healing too early — the intended lesson of the mission is that Reverse Cursed Technique converts negative energy into positive, so the encounter is designed to force you to hold your energy until the last moment.
The trial takes most players two to five attempts. Recommended preparation before entering:
| Requirement | Recommended value | Why it matters |
|---|---|---|
| Player level | 28+ | Trial enemies scale below 28 but flatten your damage output |
| Total HP | 900+ | Survives two consecutive heavy hits without healing |
| Cursed Energy pool | 250+ | Enough for 6 casts of a 40-cost technique plus dodges |
| Technique loadout | 1 ranged, 1 defensive | No healing skills — they are disabled inside the trial |
| Consumable slots | 3+ healing items | Your only recovery during the encounter |
How to confirm the technique is actually available
After the trial’s completion screen, the technique does not automatically equip. Three confirmation checks will tell you whether the unlock registered:
- Technique Menu: Open the menu and look under the Support tab. Reverse Cursed Technique should appear with a small orange “New” marker on its icon.
- Skill tree: The Cursed Energy Control branch will show a connected node labelled “RCT” now lit rather than greyed out.
- Loadout screen: If you can drag the technique into a hotkey slot without the game rejecting it, the unlock is confirmed server-side and will persist across sessions.
A common false alarm: if the technique shows in the menu but greys out when you try to assign it, you most likely have zero unspent technique slots. Reverse Cursed Technique uses a Support slot, not an Attack slot, so free Attack slots will not help.
Progression steps in the order that saves the most time
If you are starting from a mid-game save and want the technique as fast as possible, this order minimises backtracking:
- Check your Cursed Energy Control level. If it is below 10, farm shards first — every other step is wasted until this is done, because the trial will simply not be offered.
- Push the story to Shibuya Descent. Do this after the stat is at 10, since the mission itself drops roughly 3–4 shards and some free stat XP.
- Bank enough consumables. Buy or craft at least three healing items before entering the Hidden Wards.
- Talk to the Awakened Tutor and accept the trial. Read the objective text, which explicitly tells you not to heal prematurely.
- Clear the encounter, then return to the tutor to hand in the trial. The unlock is awarded on hand-in, not on the boss kill — a point many players miss.
- Assign the technique to a Support slot and bind a hotkey.
A worked example of the cost: casting the technique heals for roughly 35% of max HP at 40 Cursed Energy. With a 250-point pool and 12 energy per second regeneration, you can cast it six times in a sustained fight and recover to a seventh cast about 27 seconds after the pool empties. That is the practical reason level 10 in Cursed Energy Control is required — below it, the regeneration rate makes the technique unusable in extended fights even if you somehow obtained it early.
Ownership realities and common mistakes
Reverse Cursed Technique is not a fire-and-forget upgrade, and understanding how it behaves in practice saves a lot of frustration:
- It is not a passive heal. It heals on cast only, and the cast has a short wind-up you can be interrupted during.
- It does not scale with Attack stats. Investing in offensive nodes to make the healing stronger is a waste of shards; only Cursed Energy Control and the healing-specific nodes affect it.
- Consumables still matter. The 40-cost cast is expensive relative to a cheap healing item, so most players keep both — the technique for in-combat emergencies, items for between fights.
- It carries a brief cooldown. Spamming the hotkey will simply fail silently; the icon dims during the cooldown window.
- Respecs can lock you out temporarily. If you refund points below Cursed Energy Control 10 after unlocking, the technique stays in your menu but greys out until you restore the stat. It is never lost permanently.
The most common mistake is attempting the trial with a full offensive build and no consumables, because healing skills are disabled inside the encounter. The second most common is killing the trial boss and leaving without handing in the objective — the reward is not granted automatically.
Frequently Asked Questions
Can I get Reverse Cursed Technique without beating Shibuya Descent?
No. The tutorial tooltips suggest it is purely a stat unlock, but per the game’s official patch notes the story flag from Shibuya Descent is a hard requirement. You must complete the mission, not just reach it, before the Awakened Tutor will offer the trial in the Hidden Wards.
What level of Cursed Energy Control do I need exactly?
Level 10, with no partial credit for level 9. Reaching level 10 costs 21 skill shards total from scratch, and the tenth point is deliberately more expensive at 5 shards. Below level 10 the trial simply will not appear.
Why is Reverse Cursed Technique greyed out after I unlocked it?
The two usual causes are having no free Support technique slot, or having respec’d your Cursed Energy Control below level 10. Check your loadout slots first — the technique uses a Support slot, not an Attack slot, so spare Attack slots will not help.
How much Cursed Energy does Reverse Cursed Technique cost?
Each cast costs 40 Cursed Energy and heals roughly 35% of your maximum HP at base. With 12 energy per second of regeneration and a 250-point pool, that works out to about six casts in a sustained fight before you run dry.
Does Reverse Cursed Technique scale with my attack stats?
No. It scales only with Cursed Energy Control and the dedicated healing nodes in that branch. Spending shards on offensive nodes to improve the heal is a common and costly mistake.
Will I lose the technique if I respec my build?
You will not lose it permanently, but it will grey out and become unusable if your Cursed Energy Control drops below level 10. Restoring the stat to 10 re-enables it immediately, with no need to repeat the trial.
