Shulker Upgrades

Install modules in the sidebar upgrade slots of an Enhanced Shulker Box. Only modules in those slots are active; copies left in main storage are inert.

Higher tiers unlock more slots (1 / 2 / 3 at tiers 2 / 3 / 4).

Stack Depth

Raises per-slot stack limits. Only the highest-tier stack depth module applies if several are installed.

Module	ID	Stack limit
Stack Depth Upgrade Mk I	`cesg:stack_depth_upgrade_t1`	128
Stack Depth Upgrade Mk II	`cesg:stack_depth_upgrade_t2`	256
Stack Depth Upgrade Mk III	`cesg:stack_depth_upgrade_t3`	512

Limits scale proportionally for non-64 stacks (e.g. 16 → 32 / 64 / 128).

Filter Upgrade

Restricts which items can enter the box. Click the filter configuration slot with any item or a Create filter (not consumed). Empty-hand click clears. Empty filter = accept all.

Station filters still apply first when the box is docked.

Recipe ID: cesg:filter_upgrade

Compacting Upgrade

Merges partial stacks on insert (GUI and automation). Automation merges up to 64 items per pass.

Recipe ID: cesg:compacting_upgrade

Smelting Upgrade

Items inserted are stored as their furnace result (ores → ingots, food → cooked). Items without a smelting recipe store unchanged. Multi-step chains can progress (e.g. cobblestone → stone → smooth stone).

Recipe ID: cesg:smelting_upgrade

Void Upgrade

Overflow of item types the box already stores is destroyed instead of rejected. Types the box does not store are still rejected; a full box is not a general trash can.

Click the module’s crimson config slot with an item to void only matching overflow (independent of the storage filter).

Recipe ID: cesg:void_upgrade

Magnet Upgrade

Pulls nearby dropped items into a placed box (only items the box can accept). Only the highest-tier magnet applies.

Module	ID	Range	Speed
Magnet Upgrade Mk I	`cesg:magnet_upgrade_t1`	4 blocks	normal
Magnet Upgrade Mk II	`cesg:magnet_upgrade_t2`	7 blocks	faster
Magnet Upgrade Mk III	`cesg:magnet_upgrade_t3`	10 blocks	fastest

Crushing Upgrade

A placed box runs Create crushing and milling recipes on its own contents (ores → crushed ore, cobblestone → gravel → sand), chaining to a terminal form over successive passes. Outputs go back into the box. Only the highest installed crushing tier applies. Processing pauses while the GUI is open; if outputs don’t fit, the input is held until there is room.

Stacks with Smelting and Washing (e.g. crush ore, then smelt to ingot).

Module	ID	Throughput
Crushing Upgrade Mk I	`cesg:crushing_upgrade_t1`	1 conversion/sec
Crushing Upgrade Mk II	`cesg:crushing_upgrade_t2`	2 conversions/sec
Crushing Upgrade Mk III	`cesg:crushing_upgrade_t3`	4 conversions/sec

Washing Upgrade

A placed box runs Create splashing (bulk washing / fan) recipes on its contents — gravel → flint and nuggets, sand → clay, crushed ore → extra nuggets. Same placement, chaining, hold-when-full, and tier rules as Crushing.

Module	ID	Throughput
Washing Upgrade Mk I	`cesg:washing_upgrade_t1`	1 conversion/sec
Washing Upgrade Mk II	`cesg:washing_upgrade_t2`	2 conversions/sec
Washing Upgrade Mk III	`cesg:washing_upgrade_t3`	4 conversions/sec
