Reward boxes and Skill Crystals · 1.21.1

Minecraft 1.21.1 / AoA 3.7.16.1. Rune Boxes, Shiny Boxes, Crystal Boxes, Gem Bags and Treasure Boxes have different reward tables. This guide shows all 53 entries across the five tables, explains rolls versus item counts, and helps you use Skill Crystals without mistaking their level threshold.

Open a box safely

1. Make room in your inventory and stand somewhere dropped overflow can be collected safely.
2. Hold the box and use it. The server generates the matching gift-table loot and gives it through AoA's inventory helper.
3. Outside Creative, the checked box-use methods consume one box, not the whole held stack.
4. Inspect the result before opening more. Random rolls can repeat the same reward; a panel of possible items does not mean the box gives every pictured item.

The inventory helper attempts insertion and can drop overflow. This is not guaranteed protected storage in a full inventory. These are in-game items, and this guide concerns their shipped game rules only.

Where the inspected resources reference them

• Rune Box and Shiny Box: both occur in the checked Fishing Cage catch table.
• Crystal Box, Gem Bag and Treasure Box: referenced by the shipped water_default hauling-spawn pool.
• Crystal Box, Shiny Box and Treasure Box: referenced by precasia_water.

The latter are AoA hauling-pool definitions, not a claim that an ordinary vanilla rod always uses them or that every listed reward is available at every skill level. Their entries have their own level, weight and luck parameters. Follow the target release's fishing equipment and pool-selection rules. This resource scan does not establish a guaranteed acquisition route or exclude code-generated sources.

Read rolls, weights and stack counts separately

• A roll selects an entry from a pool.
• A weight is relative to the other eligible entries, not a percentage by itself.
• A count is how many items the selected entry awards.
• Several rolls can select the same item. The final inventory can merge matching stacks.
• All five inspected tables have zero bonus rolls. Pack changes and applicable loot modifiers can still change the final outcome.

Rune Box

One roll selects one of 14 equally weighted rune types, then awards 5–10 of that rune. It does not award 5–10 of every rune. Under this unmodified base pool, each type has a conditional 1/14 share.

Selected reward	Base weight	Count per selected entry
Wind Rune	100	5–10
Fire Rune	100	5–10
Water Rune	100	5–10
Wither Rune	100	5–10
Energy Rune	100	5–10
Lunar Rune	100	5–10
Kinetic Rune	100	5–10
Distortion Rune	100	5–10
Poison Rune	100	5–10
Strike Rune	100	5–10
Power Rune	100	5–10
Storm Rune	100	5–10
Life Rune	100	5–10
Compass Rune	100	5–10

Shiny Box

The pool makes 2–5 rolls. Each selected entry has a base count of one ingot. Repeated ingot types are possible.

Selected reward	Base weight	Count per selected entry
Iron Ingot	75	1
Gold Ingot	60	1
Netherite Ingot	55	1
Limonite Ingot	80	1
Shyrestone Ingot	10	1
Varsium Ingot	50	1
Mystite Ingot	35	1
Lyon Ingot	35	1
Ghoulish Ingot	20	1
Ghastly Ingot	20	1
Emberstone Ingot	50	1
Elecanium Ingot	20	1
Blazium Ingot	50	1
Baronyte Ingot	50	1
Skeletal Ingot	50	1
Lunar Ingot	20	1

Crystal Box

One roll selects one Skill Crystal. The weights total 460; Giant has weight 10, not a 10% chance. Read the use rules below before spending crystals.

Selected reward	Base weight	Count per selected entry
Giant Skill Crystal	10	1
Large Skill Crystal	40	1
Medium Skill Crystal	130	1
Small Skill Crystal	280	1

Gem Bag

The pool makes 1–4 rolls, each awarding one selected gem/mineral item before modifiers. Four rolls do not guarantee four different types.

Selected reward	Base weight	Count per selected entry
Diamond	50	1
Emerald	35	1
Lapis Lazuli	85	1
Prismarine Crystals	70	1
Nether Quartz	75	1
Amethyst Shard	60	1
Jade	40	1

Treasure Box

One roll selects a reward entry. Several entries then choose a stack count. A Utopian armour entry awards its one listed piece, not the complete set.

Selected reward	Base weight	Count per selected entry
Copper Coin	75	4–10
Silver Coin	50	1
Limonite Ingot	50	3–7
Bottle o' Enchanting	30	3–10
Magic Mending Compound	5	1–3
Magic Repair Dust	10	1
Gold Coin	6	1
Diamond	10	2–8
Utopian Helmet	5	1
Utopian Chestplate	5	1
Utopian Leggings	5	1
Utopian Boots	5	1

Skill Crystals: which skill receives the XP?

A Skill Crystal does not let you freely choose a skill in the inspected use path. It chooses the lowest-level eligible skill whose level is at least 15 and below 1,000. Skills below 15 are skipped, even if they are your absolute lowest skill.

Examples:

Your skill levels in the example	Result
1 and 14	No eligible skill; the failure branch does not consume the crystal.
1, 15 and 30	The level-15 skill is selected, not level 1.
14, 80 and 16	The level-16 skill is selected.
999 and 1,000	The level-999 skill is selected.
All at 1,000	No eligible skill.

Equal eligible levels retain the first skill encountered by the source iteration. Do not promise an alphabetical tie-break or a stable player-controlled choice.

Crystal sizes

Crystal	Source fraction of the selected level's XP requirement
Small	1/15, about 6.67%
Medium	1/12, about 8.33%
Large	1/8, 12.5%
Giant	1/4, 25%

The helper multiplies the XP requirement for the selected skill's current level by the fraction. This is not a fraction of the XP still missing from its progress bar, and it is not a fixed number of levels. The call requests XP-buff ignoring; the complete event/configuration path still matters when testing a modpack.

After the eligible-skill branch runs, one crystal is consumed unless the player has infinite materials. When no skill meets the threshold, a message is sent and that branch does not shrink the held stack. A crystal can therefore be saved until a skill reaches level 15.

Common misunderstandings

What happened	Explanation
Rune Box gave only one rune type	Its one roll selects a type; 5–10 is that type's stack count.
Shiny Box produced repeated ingots	Multiple rolls do not mean unique selections.
Crystal did not train my level-1 skill	Below-15 skills are excluded from selection.
Treasure Box did not give an armour set	Each Utopian piece is a separate entry in a one-roll pool.
My expected percentage did not match	Base weight is not a percentage; count, rolls, eligibility and modifiers are separate.
Items landed on the ground	Leave room for output; inventory overflow can be dropped by the helper.
