I can make the self-sacrifice. I made the other one for sacrifice others instead. Seems they can be dynamically swapped around though, so will make an alternate set and try again.
Hunger can be beat pretty easily. The issue isn't so much the total (though that's the proximate cause to the difficulty: the altar only holds something like 25% of what is needed) as it is the rate at which the points are consumed by the altar to infuse the gold block. On tier 2 I could easily replenish my LPs as fast as they were drained. Not so with this one. And from what I can tell you take a penalty if the points aren't in the pool when the altar tries to suck them up.
This is certainly an interesting gate to the next tier.
Pretty sure the Magician's Orb is needed to make the augmented capacity runes.
