Safekeeper Magus [Skill]
The nice thing about your mind is that you don't have to pay rent to live there.
Prerequisites: Safekeeper Adept, 12th level
Benefit: The dimensional pocket you maintain no longer opens when you die unless you will it. Storage is expanded to about 125000 cubic ft, or roughly a 50-ft cube. Air replenishes slowly but steadily and is sufficient to sustain up to 6 people indefinitely. Safekeeper Magus is not appropriate for all campaigns, and should be explicitly cleared with your GM.
