... using the rules in Unearthed Arcana. Here's what I have so far:
Making the ritual spell to sink a small island- How about, turning the land into water permanently? Each time you double the amount affected, DC goes up by 3. Here's how it works.
20 cubic feet... 2.714 feet on a side... 20*(2^0)
...
20480 cubic feet... 27.4 feet on a side... 20*(2^10)
40960 cubic feet... 34.4 feet on a side... 20*(2^11)
81920 cubic feet... 43.4 feet on a side... 20*(2^12)
...
20,971,520 cubic feet... 275.4 feet on a side... 20*(2^20)
...
21,474,836,480 cubic feet... 2779.4 feet on a side... 20*(2^30)
...
21,990,232,555,520 cubic feet... 28,016.4 feet on side... 20*(2^40)
DC + 120 to make a transmutation incantation affect a 5-mile-plus cube of matter.
Cool. Now, we need to make the duration from rounds to permanent- DC + 22.
Next, we need the spell to be cast from miles away- Range to long, then + 2 DC for each extra 100 feet of range. To affect the entire island, it all has to be in-range... So the range has to be five miles plus the distance between the island and the evil stronghold, perhaps another fifty miles. 55 miles = 290,400 feet. Let's say our caster is 16th level. His long-range spells have a range of 400 feet + (40*16) feet, or a total of 1040 feet. That leaves 289,360 feet for... A DC modifier of + 5788. Ouch.
Let's add it up:
32 (base for Transmutation)
+120 (affect 22 trillion cubic feet)
+22 (Permanent duration)
+5788 (Range to 290,400 feet)
______
5962 DC Knowledge(Arcana) check. Eight of them, in fact.
Now let's see what we can do to make this castable...
First, increasing the casting time. -1 DC for each hour between checks. This incantation will require eight checks to complete... The most we can do is three hours in between each, for -24 to the DC. Only one island disappears per day, I guess.
Next, the focus and material component. A 25,000 gp focus decreases DC by 2, and a material component worth 5,000 gp does the same. -4 to the DC.
Secondary casters? Well, 200 of them reduces the DC by 10, and each additional 100 reduces it by 2 beyond that... This person only has a little over 700 minions, so DC -20.
5962 - 48 is still 5918... It's obvious we need to decrease the range.
What is it's only five miles of range, and they're already ON the island... or beneath it? Someone with access to this spell would certainly have the resources to tunnel into the ground, perhaps with minions disguised as miners, and then put a teleportation circle down there. Link it to evil stronghold of choice, and instant way in and escape route!
Ooh, and we don't need five miles at all- Just over 3.5 if you're in the direct center.
That changes our 5788 into 350. Now our incantation's DC is 480. Still impossible for our level 16 villain...
Who, incidentally, needs the DC to be 34 or less to take 10 on it.
So, what could we do to decrease the DC by 446?
It's clearly impractical to get another 22,300 minions.
We don't want to take 892d6 of backlash. No, Sir.
Nothing else that self-stacks is listed... so maybe 480 is good enough, and he just needs to boost his intellect by 892 through magic items, etcetera? Doesn't make sense to me.
Any ideas? I was having fun doing this for a while now, but I'm stuck. Help appreciated.
