Spell Columns & Purchasing New Slots

[IMoriarty]

In the case where someone has purchased a four column and no other spells, ie: four ninths with no slots at five. They then purchase a fifth spell slot at first.

At this point, is it legal to purchase a sixth first spell slot, or must they purchase a fifth second level slot?

Yes, for the same reason that your first two spell purchases are 1st level, followed by your first 2nd level; namely, you’re following a pyramid shape. In theory, you could build up two columns at the same time, rather than one at a time.

So, the part I get stuck on is ARB: p 51:

"Once you have purchased four Spell Slots of any particular level, you need not buy any more Spell Slots of that level. Imagine now the pyramid being an obelisk like the Washington Monument.
You may buy more than four Spell Slots per level but there must always be at least as many Spell Slots below that level in order to support the new amount.
Further, the pyramid must be constantly building, which means that the level above must have only one less than the amount you are buying.
So in order to buy a fifth 2nd level Spell Slot, you must have a fifth 1st level Spell Slot and a fourth 3rd level Spell Slot. "

The line seems to indicate that the 6th first is illegal.

Ha! I knew I had asked a question like this before.

ARC ruled that a 2 Spell gap is legal, as long as your build has no more than a single 2 spell gap. So you can buy the 6th 1st, as long as it’s the only two spell gap in your build.
