# Non-Vanilla Mechanics To keep the economy competitive and optimize server performance, Foundation Craft deviates from vanilla Minecraft in a few important ways, all of which are documented here. ## Gameplay Mechanic Changes *** * Villager breeding is disabled in all worlds * Allay breeding is disabled in The Frontier * Mobs will not spawn naturally in claimed plots * Withers cannot spawn near unbreakable blocks * Mobs and items cannot travel through [End Portals](https://minecraft.fandom.com/wiki/End_portal) * Building and mob spawns are disabled on [The Nether](https://minecraft.wiki/w/The_Nether) roof * Players will die if they log out while engaged in player-versus-player combat * [Zombie villager curing](https://minecraft.wiki/w/Tutorial:Curing_a_zombie_villager) is nerfed by clearing villager reputations during restock ### Ominous Events Players may trigger at most one [ominous event](https://minecraft.wiki/w/Ominous_Event), such as a [raid](https://minecraft.wiki/w/Raid) or [ominous trial](https://minecraft.wiki/w/Ominous_Trial), per 12 hours. This is necessary to prevent players from building over-powered (OP) farms in The Wilderness. ### Ores In The Wilderness Players are not allowed to place any ore blocks (aka "ores") in The Wilderness, as doing so introduces exploits to the [skills system](/additional-features/skills-system.md) perks which could be exploited for an unfair competitive advantage. ### Villagers Getting Sick Villagers in The Wilderness have a small chance of getting sick when restocking their trades. When a villager gets sick, they may get other nearby villagers sick causing them to die. This de-incentivizes players from aggregating a large number of villagers in the same location in The Wilderness. ### **Mob Spawn Limits** There are a finite number of mobs that can spawn in each location on the server. If there are too many mobs in one area then new mobs will be temporarily restricted from spawning in that area. The limit is different for each world but this restriction should not impact normal gameplay. ### Wealth Transfer Limits As documented on our [Server Rules](/server-rules.md) page, there are limits on how much wealth players are allowed to transfer to other players. In most cases, the server will automatically enforce this rule. ### Removing Dropped Items The server will automatically remove all low-value items dropped in a chunk when the chunk is unloaded. This helps mitigate lag and does not apply to items dropped when a player dies. ## Block Placement Limits *** There are limits on how many blocks of certain types can be placed in settlements, homes, and wilderness plots for each of the following types of blocks: pistons, hoppers, minecarts, armor stands, brewing stands, furnaces (blast furnaces and smokers), storage containers (chests, barrels, and shulker boxes), and redstone blocks (repeaters, comparators, observers, dispensers, and droppers). ### Settlement Limits Settlement limits are based on the settlement's upgrade level, meaning that the limits for your settlement will increase each time you upgrade it. You can view the current limits for your settlement using the `/s limits` command. ### Home Limits Home limits are based on the number of plots claimed by the home, meaning that larger homes will have higher limits. You can view the current limits for your home using the `/h limits` command. ### Shop Limits Shop limits are based on the number of plots claimed by the shop, meaning that larger shops will have higher limits. You can view the current limits for your shop using the `/shop limits` command. ### Market Limits Unlike homes and shops, each of which have their own limits which are separate from the settlement limits, markets do not have their own limits and share the limits of their settlement. ### Plot Limits You can view plot limits in The Wilderness using the `/plot limits` command. This command is also available in The Frontier, although limits in The Frontier are not based on plots, so this command will simply tell you how many limited blocks have been placed in the plot. {% hint style="info" %} Players are not allowed to place pistons or minecarts in The Wilderness. The reason for this is that placement of these blocks can be used to bypass block placement limits. {% endhint %} --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
