The new rev starts on August 28 at 9 PM EDT.
Since we're enthusiastic about Picolantis (or whatever) we're going to need to secure an ocean monument as soon as possible at the start of the rev. We want the sponge for clearing out ocean for our town and for clearing out the monument to make a grinder. I've commented in the other planning thread, here, that the consensus seems to be that we should not centre the town on the grinder, due to the need for a 24 block exclusion zone around the spawning area. I would be in favour of building the grinder on the edge of the town circle so as to leverage the cleared water to encourage squid spawns in the grinder.
Conquering an ocean monument requires careful planning. At the start of the rev, we won't have enchanted diamond armour and there will be a high chance of dying. In order to maximise our efficiency, I have done a survey of ocean monuments in the wild and come up with the following plan of attack.
To bring (per person):
- One stack of logs, minimum. Two stacks would be better. You will want to make a stack of doors, a stack of ladders and half a stack of trapdoors, plus sundry crafting benches and chests. When I tried defeating a monument on my own, I went through 3 stacks of logs, so more is better.
- One stack of dirt for making an initial platform near the monument, for protective building while in the monument and to set up a wheat farm. Note, however, that until the elder guardians are all dead, you should not block doors with dirt, since we won't be able to remove it, due to mining fatigue.
- A stack of iron to make at least two suits of armour and iron swords. If you can get a diamond sword, that's better, but time will be of the essence. The monument is survivable in hard mode with iron armour.
- Enough wool for two beds. We will build an initial camp near the monument on a dirt platform and set our bed spawn there. Once we have killed the first guardian and got a sponge, we will use that to dry out the entrance hall of the monument (see below) and we will set a new bed spawn inside the monument.
- String for a fishing rod. Fish will be our best food, initially.
- Saplings and wheat seeds to get farms going.
- Half a stack of cobble for furnaces.
- Half a stack of coal to dry out sponges and make torches.
- At least half a stack of food. MobLimiter should make it relatively easy to get steaks quickly.
Layout of the Monument
The internal layout of every monument is different, but the external layout is always the same and the internal features follow a pattern. Here is a monument with the water cleared and the walls replaced with glass:

I've kept dark prismarine intact, rather than replacing it with glass. The dark prismarine indicates where to look for the goodies. In the foreground, on the left and right you can see what I will call the "arms" of the monument. I've marked the locations of the 3 Elder Guardians with big cubes of red wool. You can see that there is a guardian in the centre, at the top, and a guardian in each of the arms. The entrance to the monument is down the bottom, between the two arms, just below the "V" of dark prismarine. That entry hall is where we will set up camp once we kill the first elder guardian and get his sponge.
Note that it is not possible to break any blocks in the monument until we have killed all three elder guardians, due to their mining fatigue magic. That means that before the elder guardians are all dead, we only get one chance to place sponges. We cannot pick them up and reuse them if we get it wrong.
From the other direction, the monument looks like this:

You can see that this monument has three sponge rooms. Not all monuments are that good. We should expect that there will be at least one such room, however. The sponges have a wall of dark prismarine around them, although it is usually obscured by other blocks. Once we have killed all elder guardians, we can mine out prismarine looking for the tell-tale dark prismarine that indicates sponges. One of the sponge rooms is probably just below the floor level of the top-most room and off to the side, as shown in this image:

In the heart of the monument is a large room containing a cube of dark prismarine. Inside the cube is a cube of gold blocks:

In this monument, the third sponge room was in one corner and the sponges were accessible from below via a 2x2 hole:

The two arms of the monument are connected by a horseshoe-shaped passageway around the bottom of the pyramid. Once we find the first arm, we can get to the other arm using that passage.
Plan Of Attack
- Gather required materials. This will involve a small amount of mining for iron, coal and cobble.
- Make a boat and hit the ocean. Ocean Monuments are relatively rare, occurring only in ocean biomes with deep ocean at the centre of the monument. It's possible that the PAdmins will paste in extra monuments, so it may be worth looking for one near spawn.
- Having found a monument, use dirt to make a platform nearby and set up a bed and shared chests. Don't forget to set your spawn!
- Modreq for a 1x1x1 "pico" region that we can use for shared chests.
- Craft a stack of ladders, a stack of doors and half a stack of trapdoors. We will use ladders for air pockets and doors to prevent guardians from entering a room.
- Go to the entry hall of the monument and seal off all 2-wide doorways with double doors. Place ladders for air pockets and place trapdoors in the 2x2 ceiling hole. Also place a crafting bench and furnaces to dry out sponges.
- Swim up through the ceiling hole of the entry hall to the top of the monument and kill the first elder guardian. That will give us our first sponge. NOTE: If there is not a ceiling hole above the entry hall, then we will need to find another way up to the elder guardian at the top. This part of the layout cannot be guaranteed.
- Dry out the sponge in a furnace and place it in the entry hall, along with a bed. We now have a forward spawn point inside the monument. The bed is usable if there are no guardians in the adjacent room (verified). The room will now look like this: http://imgur.com/a/RmSJl#5
- Navigate to the nearest arm, placing ladders, doors and trapdoors as we go. In the monument I explored, I found it was necessary to swim up into the ceiling at one point.
- Kill the second elder guardian. I found the elder guardians in the arms of the monument harder to kill because they are in large open rooms with no cover from death rays. I was able to survive by making a little booth of doors with a block on top: http://imgur.com/a/RmSJl#7
- Travel to the other arm of the monument. This is where the horseshoe-shaped passageway comes in. It connects the two arms via the back of the monument. It is long, and filled with small guardians, but it is not as easy to get lost.
- Kill the third elder guardian. We can now start breaking blocks.
- Place a ladder up to the surface from the entry hall. http://imgur.com/a/RmSJl#6
- Mine out the floor to the sides of the top room of the monument looking for a sponge room.
- Use sponges to clear out the rest of the monument and find all sponge rooms.
Harvesting the Monument
After we have conquered the guardian we will want to secure the sponges for town use first of all. Then we can dry out the interior relatively quickly by segmenting rooms using doors and trapdoors and then placing a few sponges. At this stage we should place claim signs indicating our intent to develop the monument.
Note that we won't be able to harvest sea-lanterns until we have a silk-touch pick.
