CoF Rework - Best Lenses and Interactions You Probably Overlooked | Last Epoch Season 5

Storyline / Context

• Game: Last Epoch (Season 5)
• Focus includes:
  • A “COF rework”
  • Updated interactions with Prophecy “lenses”
• The video centers on how to choose lenses for different target-loot outcomes.

Core Gameplay Focus (What the video teaches)

The speaker reviews which lenses are best and which are likely not worth using after the Season 5 COF rework.

Main decision rule (TL;DR):

• If a lens is meant to do a specific thing, it will usually be best at doing that thing, based on its described effects.

Best Lenses (and what to use them for)

1) Lens of Curiosity (best for very rare uniques / super-rare targets)

Use case:

• Farming super rare uniques, especially those introduced/featured in the patch.

Premier targets mentioned:

• Orian’s Eye, Red Ring, Ravenous Void, Eternal Font, Gift of the Adelon, Death Stance (Names may be partially misheard, but are explicitly listed in the video.)

Reasoning:

• Uses a reroll chance multiplier.

Comparison stated:

• Orian’s Eye setup shown as about 2.02x multiplier (via TunkLabs).
• Next best noted as Lens of Irony (about 100% drop multiplier), but it consumes more favor, so Curiosity is preferred for these goals.

---

2) Lens of Quality (best for high LP, but not universally)

Use case:

• Chasing higher LP (Legendary Potential) via prophecy/unique mechanics.

Key warning:

• It is not automatically best for all LP goals.
• Some uniques have an internal rule where LP chance depends on legendary potential level.
• Low-LP uniques may have their 0 LP chance removed already by COF rank effects, limiting Quality’s usefulness.

Practical thresholds from the video:

• Works well starting around ~65 LP+ at COF rank 8.
• Below that (low-LP uniques): Lens of Quality becomes bad because you already eliminate 0 LP chance.
• Corruption interaction:
  • Better at lower corruption
  • Less good at higher corruption

General recommendation:

• Many players stop raising corruption around ~1000 and farm there.

High-LP example:

• For Red Ring LP range, described as approximately a 2.1x multiplier for chance / relevant LP outcome.

3) Lens of Tyranny (favor spending / “big drop multiplier” tool)

What it does (simplified):

• Consumes favor to charge prophecies faster.
• Essentially described as:
  • “consumes favor to give double the favor gain.”

Why it matters:

• Described as the main way to spend favor for reward outcomes (aside from a “COF vendor,” said to be unused).

How to use:

• Swap in only when you have enough favor.
• Spend it, then switch back to lenses with better average effects once favor is lower.

---

4) Celestial scales / duplication-style lenses (strong generic multipliers)

Lens of Celestial Scales

• ~80% chance for twice as many items

• Also includes a 2% chance to replace drops with a “Gorul/Growl egg” (uncertain what this item is; value may vary)

• Speaker’s estimate suggests effective duplication odds may be slightly lower if the egg outcome is undesirable.

Lens of Solarity / Lens of Duplication

• Treated similarly as general-purpose:
  • One described as ~40% chance to duplicate
  • Another described as giving faster prophecy charging (multiplier-like effect)

Lens of Charity

• Prophecy synergy: other prophecies charge 10% faster
• Usage idea:
  • If you have multiple prophecy reward slots but want to focus on certain rewards, Charity helps cycle those options faster.

---

5) Lens of Origin / Lens of Finality (affix-tier boosting for exalteds & altar farming)

Use case:

• Increase the average tier of affixes on items.

Suggested usage:

• Exalted farming
• Idol Altar farming
• Prophecies tied to idols/altars

---

6) Lens of Anomaly (niche case)

Effect:

• Compresses affix rarities:
  • Super-rare affixes become more common
  • Common ones become less common

Only real suggested use:

• Possibly on very rare idol affixes, example: elemental bee-type summoning idols.

Speaker’s stance:

• Not a major must-use; uncertain if other lenses outperform it due to their larger multipliers.

Lenses Likely Not Worth Using (as stated)

Lens of Acceleration

• Can be triggered by killing rare enemies, but:
  • Prophecy rewards are easy to trigger via other common activities (shrines, rift beasts, etc.)
• Seen as not valuable except possibly for niche race scenarios.

Lens of Prowess

• Targets rare/exalted helmets
• Increases chance for “level of skill” affixes
• Speaker believes it’s poor because “runescape of havoc” (likely Runes of Havoc) makes skill levels easier to obtain via gear/runes.

Lens of Anomaly (general)

• Also described as having limited use (beyond the niche case above).

Practical “Loadout” Recommendations (recap)

General setups (most cases)

• Use Lens of Curiosity and Lens of Quality on almost every setup
• Skip Quality if you aren’t targeting high-LP items

When you need to spend COF favor

• Use Lens of Tyranny

For generic multipliers

• Celestial Scales
• Celestial (other stated generic lens)
• Duplication
• Charity

For altars

• Use Lens of Origin (or Lens of Finality), with Origin preferred for exalts

For exalts

• Use Origin/Finality type affix-tier lenses (Origin most likely)

For very rare idols (bee example)

• Consider Lens of Anomaly
