Today I bring you: McMMO in one command. If you wish to just hop into it and see what I made, go to here to get the command to place into a command block. However, if you wish to see more detail on this, please either continue reading OR watch the attached video I made explaining this.

To start, this command adds 4 new skills to Minecraft. The skills are Mining, Herblore, Defense, and Combat. As you level, you get various perks. For mining, you get haste as you level up. Defense, you get resistance. Combat, you get strength, and an additional perk for each other skill you got at 100 when it reaches 100 (i.e.: when you have 100 Combat and 100 Defense, you get resistance 4). Lastly, there is herblore, which is all over the place for what you get. As you practice, you get more effects added on. There is a variety, but the middle range levels start adding negative effects to balance the positive effects (such as mining fatigue for water breathing).

For leveling, you get one level for every 100 XP.

To get Mining XP, you just mine naturally generated ores and stone (so if you place an ore then remine it, you won't get the XP for it.)

To get Herblore XP, you just break single-height grass, single-height flowers, and dead bushes.

To get Defense XP, you take damage.

To get Combat XP, you deal damage.

I have a link to both the command and an explanation of how it works (both are in OpenOffice format) right here if you want to have a copy of its functionality ready for while you play Minecraft.

If this goes over well, I might try to add an addon module to add even more skills. I will also apologize in advance for using an old method of compiling the commands. The way I tried at first didn't work, and I'll need to figure out why before I do my next command.

NOTE: If you use this in a public fasion (for example, for YouTube), please credit me for my creation. Thanks.
