What I need:
a couple of scripts to make a quest feature on my server.

What does it do:
Allows the player to get a scroll[a paper item, configurable] which will have a range of rarity scrolls it could give the player.
Each scroll type has a chance for what it can give, decreasing in rarity.


Master Scrolls can give:
Fabled Quest Scroll, Mythic Quest Scroll, Legendary Quest Scroll

Expert Scrolls can give:
Uncommon Quest Scroll, Rare Quest Scroll, Fabled Quest Scroll

Advanced Scrolls can give:
Common Quest Scroll, Uncommon Quest Scroll, Rare Quest Scroll

Novice Scrolls can give:
Beginner Quest Scroll, Common Quest Scroll

Scrolls like master, expert, advanced, ill reference at this point as Unknown scrolls.
Scroll quests like beginner, common, uncommon, rare, ill reference at this point as Rarity Quests.

Unknown quest scrolls need to be able to be obtained by a command, and be able to be used by right clicking for a Rarity quest of relative rankings
Rarity quests will contain a multitude of objectives depending on rarity.

For example;
Beginner Quest Scroll could have 1-4 objectives on it
Rare Quest Scroll could have 3-6 objectives on it.

These amounts need to be configurable if possible(meaning if i decide i want Beginner Quest Scrolls, to have 2-3 later, i want to be able to modify it myself)
if not, let me know.

As for objectives, the difficulty and quantity of these objectives needs to be configurable by rarity.
Objectives will go as follows:
Walk on land
Swim in water
Cook in a furnace
Craft items
Place a specific block
Enter a specific region(needs to be compatible with worldguard regions, or an alternative region selectior if you provide one)
Fishing
Breaking specific blocks
Killing specific mobs(needs to be compatible with mythic mobs-no exceptions)

The quantity regarding these objectives as stated will need to be configurable by rarity,
meaning a Beginner Quest Scroll could ask for;
Walk 20 blocks on land
Fish 2 things

and a Fabled Quest Scroll could ask for;
Walk 2714 blocks on land
Fish 128 things
Kill 308 Pirates

and so on.
Rarity scrolls need to be progress locked to the player, meaning if someone else picks it up, they cant make progress on it.
exceptions being coop within a distance between players.

The Rarity scrolls need to be able to display the objective quantity and current progress like such;
Fish 20 things: 12

and for objectives completed, to be crossed off and no longer counted for that Rarity scroll.

if a player has multiple quest scrolls that ask for the same objective, it should be completed based on inventory position.
Meaning if slot 3 has a quest for walking 20 blocks, it takes priority over the quest in slot 22, which asks for walking 26 blocks.
it needs to be able to check for position often, incase the player reorganizes their inventory.

Quest objectives need to be done in order or priority, and one objective at a time per quest.
Meaning;
if slot 3 has a quest:
Fish 20 things
Walk 210 blocks

and slot 12 has a quest:
Fish 15 things
Kill 15 pirates
craft 12 items
craft 2 daggers

and slot 15 has a quest:
cook 2 things
fish 2 things
Walk 30 blocks

Using those numbers above, say the player fishes 23 things, crafts 1 thing, cooks 1 thing, and walks 200 blocks.
the progress should go as follows:
Fish 20 things: 20 - done
Walk 210 blocks: 200

Fish 15 things: 3
Kill 15 pirates: 0
craft 12 items: 1

cook 2 things: 1
fish 2 things: 0
Walk 30 blocks: 0

Quest objectives need to be visible in the lore of the scroll its linked to, and should show updated progress when made.

and once all the objectives are completed, the player should then be able to right click the scroll in their hand, and should
have access to a configurable reward menu.

If a player logs out, their progress should be saved.
