This question already has an answer here:
According to the Borderlands Wiki:
Cumulatively large contributions to Moxxi's tip jar will result in gifts to the Vault Hunter.
I only found this out after giving her about $1,200 (1x $1,000 & 2x $100) just for the sake of seeing what would happen. Aside from some amusing commentary, I got nothing.
So, how does this work?
- What are the thresholds at which she starts giving loot - are they set points, or is she effectively another slot machine?
- Does the "cumulative" donation need to be given in one visit, or can it be spread out across multiple stops in the zone?
- Are there any particular items that she gives, or is it just random leveled loot approximate in value to the donation level?
- Is the loot even worth it - could I sell the given loot and get anywhere close to a full return on my investment?
