Wasn't room for an example, sadly. Let's do a brief walkthrough.
Let us say your vampire has a Magic attribute of 3, a current Essence of 4, and is not an initiate. Their maximum Magic attribute is is their current Essence + their Initiate grade, or 4. Now, if your vampire loses a point of Essence (due to Essence Loss or anything else), the vampire does not automatically lose a point of Magic as a normal metahuman would, so your vampire would still have have Magic 3 and Essence 3.
Okay, so what happens if you lose another point of Essence? You still don't lose a Magic point from Essence loss, but your maximum Magic attribute (current Essence + Initiate grade) drops to 2. Since your maximum Magic (2) is lower than your current Magic (3), you lower your current Magic to your maximum Magic, i.e. your Magic drops to 2. This is a permanent Magic loss, and the lost point can only be bought back by Karma.
This is why vampires and other Infected with a high Magic attribute need to keep well fed.
If I'm reading this correctly, then you're saying that when a vampire gets low on Essence, they (assuming they are a magician), going to permanently impair themselves (barring re-purchasing with karma)?
That's going to mean any scenarios in which a PC vampire mage faces real hunger (I.e. fun situations for a GM to place a player in), is going to have long term and hugely negative effects on that character. It also means that Evil NPC Villain who you nearly kill, but fail because she's a vampire, is actually crippled by their near defeat. No coming back a few months later for revenge - they'll be busy licking their wounds for a couple of years. I suppose initiation counters that a bit, but it's a dramatic change.
It provides an interesting balance between magic using vamps and their mundane(ish) cousins because the latter will be free to spend their Essence to boost their abilities, whilst the former will be terrified to do so. But given that I can't see many players creating non-magical vampire characters (you might not want to be a mage, but who could give up Adept abilities?), it's going to be a non-issue for PCs.
Very closely related to that, it also prevents the scenario of the powerful vampire magician who boosts her Magic rating by spending Essence, doesn't it? They can add a couple of points, but no more jacking it up really high by spending lots of your Essence.
Hmmmm. Food for thought.
