And over time you'll discover that Break HP Limit is actually not very useful at all: Any attacks that go over the 9999 cap will usually still kill you if you get your HP to about 30,000 and your other defensive stats insanely high. Auto-Phoenix is considerably more useful than BHPL, but make sure you've got the right status defenses to make sure it can still be activated. Questing 60 Dark Matters for BDL is one thing... questing 99 Dark Matters for Ribbon is truly frickin' shudderworthy.
