Blueprints and crafting

What a blueprint is

A blueprint is a recipe in the form of an item. It does not stack. Every copy is separate and has its own state:

• Quality QR from 0 to 100%: it grows with successful attempts and raises the success chance and the product's minimum quality.
• Number of uses: unlimited or fixed. A blueprint with a limit loses one use on every attempt and disappears after the last one.
• Owner: a blueprint can be given away, sold or lost. The first use by a new player reassigns it to them.

The state of a copy is stored centrally, not on the item itself. A copied blueprint gives nothing: on an attempt only one copy with a given number goes through, and the others are rejected. A blueprint withdrawn from the game, or an unknown one, will not open the station.

The blueprint's description shows the level, quality, number of uses, the list of ingredients and the result.

Every blueprint also has:

• a category (weapons, machines, materials), which decides which skills grow on an attempt;
• a profession, which decides the success chance and the product's quality;
• a level from 1 to 100, i.e. the difficulty level for skill learning;
• optionally a book and a number in the book.

Crafting station

1. The player holds a blueprint in the main hand and right-clicks a crafting table. The table then opens the blueprint window instead of ordinary crafting, also when clicked with the off hand.
2. The blueprint moves from the hand into the window. A player can have only one such window open at a time.
3. The window shows:
   • the blueprint;
   • each ingredient with a "have / needed" count (green when sufficient, red when lacking);
   • the success chance, the profession with its level, the QR quality and the number of uses;
   • a mode switch, the Craft button and the Craft x10 button.
4. Nothing can be moved in the window. Ingredients stay in the player's inventory and are taken from it.
5. After the window closes the blueprint returns to the inventory, and with a full inventory it drops at the player's feet. The same happens on leaving the game, moving to another server and on restart.

Attempt conditions

• All ingredients are in the inventory. An ingredient can be a raw material (an item without quality) or a product from another blueprint with 100% quality.
• The player has at least 2 free inventory slots: for the result and for a possible new blueprint.
• Ingredients are taken from the inventory in slot order. If the player changes them during the attempt, the attempt is lost: the blueprint loses a use, but nothing is issued or taken.

Series

A series is up to 10 attempts, one every 0.5 s. It is interrupted by missing ingredients, no space, closing the window, the blueprint being used up, or leaving the game. The mode can be changed only between attempts, not during a series.

A craft attempt

1. Success roll. The chance depends on the blueprint's profession and its QR quality (formula below).
2. Success:
   • the player gets the result with a rolled quality (normal mode) or with 100% quality (100% mode);
   • the blueprint's QR quality may increase;
   • with a 2% chance the player gets the next blueprint from the same book.
3. Failure: the ingredients are lost. With a 30% chance the attempt "almost succeeded", and then every piece of every ingredient comes back separately with a 50% chance (on average half). Returned pieces have the same properties as the consumed ones.
4. Use: a blueprint with a limit loses one use, regardless of the outcome.
5. Skills: after every attempt, successful or not, a skill gain is rolled for the blueprint's category.

Success chance in normal mode

In 100% quality mode every value is halved, e.g. profession 50 and QR 50% gives 23.75% instead of 47.5%.

Modes: normal and 100% quality

Before an attempt the player chooses the mode with a button in the window. The mode affects only the product's quality; QR growth, the new blueprint and skills work the same way.

Minimum product quality

A component that is to go into another blueprint must have 100% quality. So the 100% mode, or a high profession and QR, pays off.

Blueprint quality (QR)

A new blueprint copy has QR 0%. After every success QR may increase, and the higher it is, the less often it grows. A failure does not change QR.

QR growth after the last use of a blueprint with a limit is lost together with the blueprint.

Blueprint books

Blueprints can form a book: a sequence of numbered blueprints, usually increasingly difficult. Every successful craft from a blueprint in a book has a 2% chance of giving a new copy of the next blueprint in that book, with QR 0% and the use limit from its definition. Nothing drops from the last blueprint in a book.

Special results

• Minion: quality does not matter and is not assigned. The first minion of a given type crafted unlocks that type in the player's minion collection.
• Pet: the result goes straight to the pet collection, not to the inventory. The pet's rarity depends on the rolled quality.

Product quality

Every product from a blueprint (except minions) has a quality from 0% to 100% in whole percent, visible in the description as "Quality: 73%". Raw materials, mob drops and shop items have no quality.

Effect on the item

• Durability = base durability x quality, at least 1. Applies to items that wear out and do not stack.
• Beneficial attributes (damage, armor, armor toughness, knockback resistance, health, positive item stats like Health Regen) = value x (50% + 50% x quality).
• Unfavorable attributes (e.g. attack slowdown) stay unchanged, so that a weaker weapon does not hit faster.

The item's bonus is scaled, not the player's base 1 damage. An iron sword gives +5, so at 100% a hit does 6, and at 0% it does 1 + 2.5 = 3.5.

Components

A product used as an ingredient of another blueprint must have 100% quality. A product below 100% is only good for using or selling.

Quality "laundering" block

• A product below 100% will not go into a furnace, smoker, blast furnace (also when fed by a hopper), stonecutter or smithing table.
• The anvil and grindstone will not combine two items of the same kind if either has less than 100%.
• Repair with a raw material, applying enchanted books and removing enchantments work at any quality.

Stacks

Products stack only when they are identical: the same quality and the same source blueprint.

Selling to a merchant

• The merchant pays for a product as much as the raw materials from its recipe are worth at buy prices, divided by the number of pieces in the result. Quality does not change the price.
• A component in a recipe is counted through the cheapest blueprint that makes it. An ingredient with no price and no recipe is worth 0.
• The merchant does not buy products from an unknown blueprint or items with a damaged quality marker.
• Prices and the products table: NPC shops -> Products from blueprints.

Ordinary crafting

The inventory grid, the crafting table and the crafter make only basic raw materials. Everything else requires a blueprint. A blocked recipe does not show a result.

Special recipes are blocked too, e.g. repair by combining two items in the grid, because the result would have no quality. The furnace, smoker and blast furnace work normally for raw materials.

Skills from crafting

Every attempt rolls a skill gain according to the blueprint's category. The target level is the blueprint's level, and difficulty is counted from the blueprint's profession. Gain formulas: Skills and professions.

Blueprint list

To be decided

• Where players get blueprints. Today a blueprint is given only by the administration or by the 2% chance of the next one from a book. Sources are needed: drops, rewards, shop, quests.
• Taming bait has the Materials category, so it teaches Cooking and Herbalism. To be decided: a separate category with Taming and Care.
• Skills on failure. Today a failed attempt also gives a skill gain. To be decided: whether only success should.
• Rarity and trading of blueprints. All blueprints are ordinary today and can be traded. There are no rules for rarer blueprints.
• Quality and enchanting. Quality does not affect enchanting today.
