Way of the Fruit
In theory, this perk should be effective with Bonsai, however, Bonsai seems to never provide any fruit.
With the 1.27 patch, multiple fruit can be eaten, sometimes providing up to 4 strength at a time on a semi-permanent basis (showing up on the character sheet as a bonus, but never wearing off). The extra strength seems permanent (as wandering around in the waste for weeks doesn't cause the effect to end), but can wear off at seemingly random times. This may have something to do with being irradiated while eating fruit, but even after the first mission fruit can potentially offer the permanent effect. [verification overdue]
