Marylene's Fallacy
Mechanics
Marylene's Fallacy is rather straightforward in what it does; a massive amount of critical strike multiplier in exchange for 40% less critical strike chance.
With the base 150% Critical Strike Multipler the breakeven point where Marylene's does less damage is if your base critical strike multiplier before equipping Marylene's is higher than 235% (85% additional critical strike multiplier).
This, however is changed when Critial Strike Luck from either Diamond Flask or Dance with Death is applied.
Wtih a base 100% critical strike chance, the critical strike chance with Marylene's Fallacy is 84%, following the Luck formula.

(2*0.6)-(0.6^2)=0.84=84%
In every case where your critical strike multiplier before equipping Marylene's Fallacy is higher than 390% (150% base + 240% additional) using Marylene's Fallacy is a loss of opportunity as you have to invest massively into critical strike chance.
Marylene's Fallacy combined with Luck is most effective when your pre-Marylene's critical strike chance is between 50%-80%.
As the tables below show, using Luck is extremely beneficial for Marylene's Fallacy, but tapers of as critical strike chances approaches 100% or when your other sources of Critical Strike Multiplier is high.

Version history
| Version | Changes |
| 2.6.0 |
No longer has the property non-critical strikes deal 40% less damage.
|
| 2.2.0 |
All sources of increased Critical Strike Multiplier have been changed to additional Critical Strike Multiplier. This change brings the functionality in line with how most players think it works.
Because of this, all items, passives and some skills/support gems that used to have increased Critical Strike Multiplier are now 33% less effective on players, despite having the same value. A number of these have been adjusted in value to maintain similar effectiveness.
Divine Orbs are required to update the following to their new values: All craftable Jewel mods which grant Critical Strike Multiplier, Facebreaker, Marylene's Fallacy, Fragment of Eternity (the Descent: Champions Unique), Bino's Kitchen Knife, Romira's Banquet, Shadows and Dust, Ungil's Harmony, Eclipse Solaris, Death's Harp, Mortem Morsu, The Goddess Scorned and Abyssus.
