Compare the Mutagen reward with the value of the other choices. Take the rewarded option when it fits the route; passing up a needed attack or movement choice can cost more than the currency gains.
[MW] Wombat Warrior’s May 27 comments provide the unlock report (#3) and describe rewards for designated choices (#5). The later official patch increases Rare and Epic rewards without listing their new amounts. The player’s older reward amounts and opinions about the strongest genetic are not a current reward table or ranking.
Version 1.1.1 fixed Stubborn’s tooltip sometimes being absent from Point of Interest and Evolution menus. A missing tooltip in an older recording is therefore not enough to show that the Genetic had no effect. Check which menu and version the recording uses before comparing its displayed choice with a current run; the hotfix does not announce a new reward amount. Official 1.1.1 hotfix
: Added the 1.1.1 correction for missing Stubborn tooltips in Point of Interest and Evolution menus, explaining why an absent older tooltip does not establish a different reward amount. Added questions covering “Should I always take the option that awards Mutagen?” and “Does an absent tooltip prove that Stubborn had no effect?”. The answers clarify the relevant choice while preserving the stated conditions, distinctions and attribution to the original sources.
