Tutorials/Beating a challenge map

A compilation of multiple LPer's strategies on beating a challenge map. Most of this tutorial is based on Complete the Monument styled maps, but will apply to any type of challenge map.

Terms
Some general terms used in challenge maps.

Useful things to know
These are things that would be very useful to have knowledge about when trying to beat a custom map.

Damage
Mobs become easier to kill when you know how many hits they take with your weapons. It's also good to know how much damage a weapon does if you need to know which one of your weapons is the strongest.

Fighting mobs
A general list of strategies on how to take care of certain situations.

Large groups of mobs
If there are several mobs in a group, it is best to walk backwards, away from the group (kiting). If there is a creeper within the group, let it explode, and it will kill most of the mobs within the group.

Two-hit-kill mobs
These include mobs like Zombie Pigman. If you can, build a barricade around yourself, which will prevent them from getting inside. Take them out by bow, even in close range.

Skeletons
Try and use your bow if you don't have at least a 3-hit kill weapon. As of 13w03b, skeletons will attempt to knockback players in close range by firing arrows quickly.

Blazes
Fire Resistance are extremely useful against Blazes. Don't get too close to them if you have to attack them with a sword, since they deal heavy contact damage.

Ghasts
Ghasts are extremely annoying in maps, because not only do they break blocks and set things on fire, but they also fly away from the player, making them hard to kill.

You want to dispatch of the Ghast as soon as possible, otherwise it'll get too annoying. To kill a Ghast, aim for the body, or deflect its fireballs. This is the ghast's hitbox.

Ghasts cannot break Cobblestone or anything with a higher damage resistance, so use that to your advantage. Always build with Cobblestone, if you have some.

Silverfish
Often, a mapmaker will create a passageway with walls of Silverfish Blocks. If you break one of these blocks, it will spawn a Silverfish, which, when attacked, will spawn even more Silverfish from adjacent blocks. A Silverfish will not call for help if it is killed in one shot by a player, or if it died by "natural" causes.

A Silverfish has 4 hearts of health. Here are some ways of killing a Silverfish without it spawning more Silverfish:
 * Shooting it with a fully-charged bow (4.5 hearts of damage)
 * Using a Potion of Harming II (6 hearts of damage)
 * Hitting it with a Sharpness I-enchanted Diamond Sword (4~5 hearts of damage)
 * Setting it on fire with a Flint and Steel (natural causes)
 * Burning it in Lava (natural causes)

Funboxes
These malevolent boxes cause nothing but trouble. Here's some ways to dispatch of them.

Lava
Lava is the best way to disable a funbox. It lights up the area around the funbox, preventing any spawns, and kills any monsters already spawned by the funbox.

To use lava, get within block-placing range of the funbox, and pour lava on it.

If you cannot reach the area of the funbox, build up so that you are a little higher than the funbox, and pour lava down onto the funbox.

Cannons
Using a TNT Cannon is a fun way to dispatch of funboxes. However, using these could blow up a wool chest, not to mention yourself. Be careful with this method.

Tunneling
The easiest way of tunneling toward a funbox is to go from below, as most funboxes are placed out in the open. Make sure to light up your tunnel very well while you tunnel towards it: you don't want your tunnel to be too dark.

If in a dungeon, always break the funbox before moving on. Creepers are known to blow up your lighting around the funbox and start it up again.

Big rooms
Rooms that are generally, very big. They are difficult to light up because you have monsters attacking you from all directions.

Runthrough
Drink a Potion of Swiftness, and charge into the area, placing torches where you can. This is very dangerous, but very effective as well, as you will be covering large areas, and disabling lots of spawners.

Charge and retreat
Charge in, light up the area, and retreat. Effective, but snail-slow, and rather dangerous.

Tunneling
Tunnel around the room, lighting up the walls of the room at regular intervals. This will disable most of the spawners and will make the Charge and Retreat method much easier. (It will be more effective to use Lava to disable the spawners, rather than torches.)

Tunneling to the top of the dungeon and pouring lava from above is a much safer way of doing this.

Landscapes
Even bigger than a big room, they are vast areas with several little dungeons for you to conquer. As well, there are usually areas on the other side of these landscapes, making these areas much more annoying.

Transportation
Using Minecart Tracks is a very effective way of moving around the landscape. You could also make a tunnel under the landscape for safe travel at night, but this takes a lot of time, and is not worth it.

Void rooms
Areas which open up to The Void or Lava. If you fall off of the main platforms, you will lose your inventory most of the time.

Go slow and steady in these areas. Don't take unnecessary risks. Block off any holes to the Void that you can reach, and be very careful of sand or gravel.

Bridging
If there is a gap between two platforms, make a very secure bridge. Place blocks to the left and right of you, in addition to below you.

If there are too many mobs on the platform where you are heading to, it is best to make a Piston bridge, if possible. Place a Piston facing the platform, and repeatedly have it push blocks. Do this three times: one for the floor, and two for the rails on both sides.

Mazes
Bedrock mazes are found occasionally in maps. They're frustrating to solve and hard to get out of. Here's some tips of finding the right path:

Dead end mark-off
Whenever you hit a split road, put down a torch, and then go left, or whichever direction is closest to left. Always go left. It's much easier to find dead ends if you stick to one direction.

If you find a wall, good. Traceback to where you started, and mark off that path as a dead end (either with stone blocking the way, or a torch on the beginning of the path). If you find a split road, do the same thing: mark off the split road with a torch, and go to the left choice.

Fighting in mazes
A common trick for mappers to do is to put spawners within the mazes, making it harder to move around. Use corners to your advantage when fighting in a maze. Don't use lava: it'll gum up the corridor too much.

Sand and gravel
In general, a sand or gravel trap is a trap involving floating sand or gravel. When you place a block or a torch on it, it will fall, which will either reveal lava, a pit of monsters, or fall onto a Pressure Plate, which will activate some redstone.

Sand traps that expose areas are unavoidable, however, you can avoid the redstone-style sand trap by being wary. If you see a chest, furnace, or something of that sort, make sure you have a way of getting away before breaking it.

TNT
If it's too good to be true, it probably is. Look out for innocent houses built on the landscape: it could be a deadly trap! TNT also makes a great big hole, making it rather difficult to fight. Also some maps contain TNT which acts like it did in beta, it will detonate on hit making it impossible to disarm. Map makers achieve this through external tools.

Pits
Although easy to dodge within corridors, fighting can distract you, and you can walk off the edge of a pit! Cover up, or barricade every pit you see that might be a threat. If possible direct the fighting away from any nearby pits.

Redstone-related Items
This includes Pressure Plates, Dispensers, and Pistons. Redstone circuits can be made to do virtually anything, so if you see an "innocent" Pressure Plate lying about, block it off, or avoid stepping on it.

Movement-affecting blocks
These include Soul Sand, Ice, and Vines. Soul Sand makes you walk slower through an area; Ice makes the ground slippery; Vines can be distracting when fighting against walls. Try to stay away from Soul Sand or Ice, and avoid being cornered by mobs in a vine-filled area.

Your inventory
It should contain: Two Swords A bow -> up to a stack of Arrows Two Pickaxes A stack or two of Torches Buckets (if you have some) -> A Water Bucket is good, as well as a Lava Bucket Armor (very important!) A stack or two of Blocks Wood Some Coal (or Charcoal) for Torches

Regeneration, Speed, or Fire Resistance potions are also nice things to have, if you can afford them.

In case of an emergency
Oh no! You died in an area with a high monster concentration, and you had your best items! What will you do?

Be prepared for this scenario. Always have an emergency chest stocked with pre-made resources, just in case. It should have minimal inventory: a sword, a bow, some torches, and some armor. Note that you are not trying to conquer the dungeon with this, you are simply trying to get your items back.

The base
A main base should have these characteristics: - It is completely safe from monsters. - Crafting Tables, Furnaces, and Chests is situated there.

Generally, most people build their bases around the Victory Monument, but some mapmakers have been annoyances within the monuments (e.x. dying zombies, growing vines), so it is best to build it relatively close, but not too close.

Some more things I recommend you have in your main base:

Food farm
The best type of food farm is an Automatic Wheat Farm (Tutorial), as wheat is a very easy resource to obtain, and bread is effective and easy to make. Bread is also stackable, making it easy to carry around.

Carrot farms can also be useful since you don't need to cook anything.

The next best thing is a Mushroom Farm, which produces very fulfulling Mushroom Stew (Tutorial). Using Bone Meal on regular Mushrooms will produce a big Mushroom, giving you 4~16 mushrooms! However, Mushroom Stew does not stack, taking up lots of needed space in your inventory.

A Melon farm, unless very big, is not recommended, as melons only feed one part, and melons grow rather slowly.

Monster farm
If possible, set up a spawner trap around a funbox. If you can't find a funbox near your base, set up spawning platforms. Make them really high in the air. This is to ensure they spawn.

The best kind of trap is a lava blade trap, which kills monsters and leaves their drops unharmed.

A gravity trap takes more time, but is also more effective, as there is absolutely no light near the spawners, giving full spawn rates.

Tree farm
Wood is undeniably the most important resource in Minecraft. You'll need a lot of it too, in the case of challenge maps.

Cobblestone farm
This is only needed in extreme cases, where you have a great lack of Stone to use. The easiest farm to make is
