Moxxi's Endowment (BL3) experience bonus breakpoints

In Borderlands 3, Moxxi's Endowment is an artifact with a guaranteed effect of "+N% Combat XP" and can also generate with "+M% Experience Gained From Combat", where N and M depend on the item level. This table shows the bonuses for each level where they increase (the breakpoints), which may be useful for deciding when to stop grinding and get a higher-level artifact. At low levels the experience bonus is actually negative, but Moxxi's Endowment can't normally generate at those levels. Data collected on 2026-02-15 from the Steam version of Borderlands 3 by using ZakisM/bl3_save_edit v0.1.6 to create Moxxi's Endowment at each level.

Level	Guaranteed	Additional	Total
1	-5%	-3%	-8%
3	-4%	-3%	-7%
5	-4%	-2%	-6%
7	-3%	-2%	-5%
