Map Trailer

Exploration Server IV is an open world CTM-style adventure map, with leveling and RPG mechanics, that is also an expansive modpack which makes heavy usage of mods all throughout the map. This is the fourth and final map in the series. The core concept behind the Exploration Server series is to collect a large number of builds made by other people, and showcase them by terraforming them all together into one giant cohesive game world. The map takes place on a continent 7000x6000 blocks large, with more than 15 major story dungeons, and 50+ optional mini-dungeons and other points of interest. Expected playtime to finish the map is about 150-200 hours. The map was designed with 4-6 players raiding the dungeons together in mind, but can be played with less (or even in single player), for a greater challenge.



  1. Download Minecraft Forge 1.7.10-
  2. Once Forge downloads, run it, and choose to install the Client.
  3. Download the desired version of ESIV:
  4. Navigate to your .minecraft folder (C:/Users/{Your username}/AppData/Roaming/.minecraft)
  5. If you've already installed forge in the past, you may already have a 'mods' folder and a 'config' folder. Make sure both of those are empty!
  6. Extract the contents of the zip file into your .minecraft folder, overwriting anything it asks to overwrite.
  7. Only if you are going to be playing Multiplayer: Open the file .minecraft/config/CustomMainMenu/mainmenu.json in a text editor, and find the line that says "ip" : "" underneath connectToServer. Type the address of the ESIV server you wish to play on between the quotation marks, and then save the file.
  8. Run the vanilla Minecraft launcher.
  9. Select Launch options. There should be a new profile called 'Forge'. Select that, and place a checkmark next to 'JVM Arguments'. Replace the JVM Arguments with:
    -Xms2048m -XX:NewRatio=3 -XX:SurvivorRatio=3 -XX:TargetSurvivorRatio=80 -XX:MaxTenuringThreshold=8 -XX:+UseParNewGC -XX:+UseConcMarkSweepGC 
    -XX:MaxGCPauseMillis=10 -XX:GCPauseIntervalMillis=50 -XX:+ExplicitGCInvokesConcurrent -XX:+BindGCTaskThreadsToCPUs -Xnoclassgc
  10. Save the launch settings, go back to the homepage of the launcher, and choose Forge from the Profiles dropdown.
  11. Launch Minecraft. When it finishes loading, BEGIN!!!!



  1. Download the ESIV Server.
  2. Configure the file if you need to... you know, the normal Minecraft server setup stuff.
  3. Open config/esiv.cfg and configure the spawn rate to your desire. The recommendation is 0.5 for 2 players, 0.75 for 3 players, and 1.0 for 4+ players.
  4. Create a .bat/.sh file for launching the server, with the following contents. Adjust the RAM allocation as needed.
    java -Xmx8G -Xms8G -XX:PermSize=256M -XX:MaxPermSize=512M -jar forge-1.7.10- nogui
  5. Launch the server with your batch file!
  6. The recommended scoreboard setup is below. This will show each player's current level in the online players list (Tab), and will show each player's current health on the right side of the screen:
    /scoreboard objectives add esivlevel dummy Level
    /scoreboard objectives add health health HP
    /scoreboard objectives setdisplay list esivlevel
    /scoreboard objectives setdisplay sidebar health


Important Notes / FAQ


Target Audience/Prior Knowledge:

This map does not have any "tutorial" questlines or walkthroughs for any of the included mods, and mostly throws you straight into the deep end. It is a challenging map which assumes you already have full mastery over the vanilla Minecraft mechanics and at least some familiarity with popular 1.7.10 minecraft mods. Particuarly important to this map are Tinkers Construct, Thaumcraft, Botania, and Ars Magica 2. If you do not have familiarity with those mods, the map may be very difficult to overcome.

Known Major Glitches:

Damage Formula:

You may notice when first starting the map that you seem to not be able to do damage to anything. Damage output in this map is largely dependent on the difference in level between you and the monster. Your level is shown in the top-left corner of the screen, while monster levels are shown on their nametags above their heads. With no weapon, your punch only does 1 damage. Thus, if the monster is even a single level higher than you, that 1 damage will be dropped to 0 damage... and at the start of the map, almost everything will be higher level than you. Your first priority should be to craft yourself a weapon. Even a wooden sword will give you a small amount of leeway, allowing you to damage enemies at least a couple levels higher than you. (Fun fact: If you're higher level than the monster, the damage formula will make even 0 damage weapons hurt the enemy, like snowballs)

EXP and Item Drop Policies:

When a monster is killed, the EXP for the kill is given to whoever landed the killing blow. There is no automatic EXP sharing system; the person who lands the last hit gets 100% of the EXP. There are EXP capsule items that are intended to be used for manual EXP sharing between players, such as when the levels of party members start to become unbalanced. If a monster is killed by an environmental factor, the kill cannot be attributed to a specific player, and thus no one will get any EXP. Additionally, in that case, the boss or monster will not drop any items. Environmental factors are things like fall damage, suffocation, lava, etc... It is very important to note that status effects like fire and wither are also considered environmental effects!! That means if you light an enemy/boss on fire, and the fire tick deals the finishing blow, you won't get any EXP or drops.

Protected Zones:

A few areas in the map are protected from you building/breaking blocks. If you try to break a block and it immediately reappears, or you try to place a block and it immediately returns to your inventory, it might not be because of server lag... you might just be in one of the block protected areas. (Very very few areas in the map actually have this protection applied, and it should be pretty obvious why an area is protected when it is)

Disabled Items and Restricted Items:

There are a large number of items/blocks/etc. that have had their crafting recipes removed in this map. They fall into two categories. Restricted items are still obtainable in the map, but must be found through exploration (maybe an NPC sells it somewhere, maybe it's loot from a dungeon, maybe some monster/boss drops it, etc). On the other hand, disabled items are not obtainable in any way.

Map Credits:

The map consists of a large number of builds made by other people, downloaded off of public map sharing sites, like Planet Minecraft. This is the core idea behind the "Exploration Server" maps -- showcasing all of the amazing builds by terraforming them together into a giant cohesive map that is designed to encourage thorough exploration. These builds have been used without asking permission from the original authors. Also, some of the builds have requested to not be hosted on public servers, so please keep this in mind. All of the original builds contained only vanilla Minecraft blocks, so anywhere in the map you find blocks/items/creatures from mods, you know that I placed them there myself. I tried my best to include a very wide variety of blocks and items from many different mods all throughout the map.
