Towers are tall, circular structures found throughout the world. As with Dungeons, each tower has a number of Mob Spawner-filled floors and a healthy amount of treasure at the top. Towers are found in multiple colours, including blue, light blue, yellow, red and purple; a tower's colour is often dependent on the biome it's found in. Unlike the dungeons, towers are leveled depending on the level of the area you are in. As of patch 0.5, taller towers have been added to appear on occasion, with several more levels
to conquer on your climb to the top, as well as better treasure once you reach the top room.
Be sure you're equipped before attempting to tackle one of these! You may find it more challenging than you think!
There are multiple rooms in the towers. Each has a random spawner and a different design. There are sometimes lava/water and or Soul Sand blocks on the floors. If a tower has blocks on it half way up, like a generated block (not ones that have been placed) then thats where the door will be.
The top floor always contains a red carpet to the end chest, making it a profitable and sometimes dangerous source of wool.
Some Towers may spawn with floors broken in places, causing monsters from the floor above to drop onto you. every other floor has holes in it so you don't get mobbed by mobs. Beware!
Note that if you're thinking of making it your home,there are hidden spawners above the pillars, in the ceiling. :(Occationally the end-room carpet is white insted of red, as well as all of the spawners being pig-spawners insted of the usual mob-spawners.
Lets face it: the design of the floors and their entrances, not to mention having mobs in your face while trying to get into the next room or trying to get back down the ladder makes it difficult to progress, so here are a few ways to make towers less rage inducing.
The Mage Rush: The mage rush requires the person to blink from room to the other side and climb the ladder all the way up to the top. This Is useful when fighting towers way beyond your level as this will allow you to get 10x's the items you have. But when this comes with the going down, it is rather hard as more mobs have spawned. You must carefully blink down the tower without getting swarmed by the monsters.The Midway Ladder: The midway ladder is where you rush to the midway of a ladder. As most mobs have very little range you can stay up there and shoot them with your wand/bow. After you manage to kill all of the mobs in that room you can rush back down and destroy the spawners. Then you can get on the ladder and stay half-way using your bow/wand, attempt to climb yourself up and down the ladder getting hits.(Using the Lighting Spell can be a very useful tool, but be warned that you can lose your items due to the lighting) Another Tip whilst doing this is to use the S key to climb up ladders. This is so you can face the mobs and easily go up and down.
All Balls: All Balls is where you get a diamond pickaxe and rush like a mad dog destroying all the spawners you can. This is best Done with warrior or a mage as mages can blink to dodge any attacks and warriors are quick enough to not get killed.
Also, once you get to the top, you may notice a block similiar to a note block, titled "Entrace warp". This block is possibly used to warp back to the entrance if you can't get through the top. -Rainmask64
Easy Exp FarmingEdit
There Is a way for all classes to use these abilities to get massive levels in a quick time.
All the mage/ranger has to do is wait for a lot of mobs to spawn, then they can use their lighting abilities which can do a massive attack. The Warrior can spam their Whirlwind ability as well. Using this ability a few times will usually clear most mobs around your level.
Doing this however does destroy any items that drop. Some of the items might have just been that better wand/bow/armour you needed.
And now that Frizzil has read this, he'll be addressing the issue!
Another method for farming involves setting up a short barrier between a ladder, and multiple slime spawners. If one places half slabs in the right positions, it is possible to shoot charged bolt spells, arrows, or other projectiles through, dealing damage without destroying drops, or taking any hits. If you haven't destroyed all spawners on the floors above and under your grinder, make sure to block the ladders.
This method is quite difficult to set up, but is very rewarding, because it takes very little time to make many kills, and score tons of loot. The effectiveness of whirlwind in such a situation is unconfirmed, though.
