ExponentialItemsReloaded

Adds Artifact of Exponents, an artifact that makes item stacks jump exponentially instead of increasing one at a time.

By default, with Base Size set to 2, repeated pickups move stacks like:

1 -> 2 -> 4 -> 8 -> 16 -> 32...

This is a modernized/reloaded version made for current Risk of Rain 2 modded builds.

Requirements

• BepInExPack
• R2API.ContentManagement
• R2API.Language

Installation

Place the mod DLL and icon files in the same plugin folder:

BepInEx/plugins/ExponentialItemsReloaded/
|- ExponentialItemsReloaded.dll
|- icon_selected.png
`- icon_deselected.png

Restart the game after replacing the DLL. BepInEx loads plugin code at startup, so DLL changes do not hot-reload while Risk of Rain 2 is already running.

Artifact

Enable Artifact of Exponents from the artifact menu.

If Require Artifact Enabled is turned off in config, the mod can run without enabling the artifact.

Config

The config file is generated after launching once:

BepInEx/config/com.cryptidlabs.exponentialitemsreloaded.cfg

General

Item Filters

Debug

Temporary Items

Temporary items use a different inventory path than normal permanent item pickups. ExponentialItemsReloaded now hooks Inventory.GiveItemTemp directly and reads temporary/effective stack counts from RoR2's temp item APIs before calculating the next exponential target.

To enable temporary item scaling:

1. Launch once so the config exists.
2. Open BepInEx/config/com.cryptidlabs.exponentialitemsreloaded.cfg.
3. Set Affect Temporary Items = true.
4. Restart the game.

When enabled, temporary grants should follow the same configured exponential stack behavior as normal item grants.

Notes

Temporary items and tierless/hidden items can be chaotic with heavily modded profiles. Keep those toggles off unless you are testing or intentionally want those systems affected.

If you change the plugin GUID from an older local build, delete the old config file so the new one can generate cleanly.

Changelog

1.2.8 Temporary Grant Fix

• Added direct handling for RoR2 Inventory.GiveItemTemp grants.
• Temporary item scaling now uses GetItemCountEffective, GetItemCountTemp, and GetTempItemRawValue instead of relying on temporary-looking item names or tiers.
• Fixed temporary grants staying at 1 when the item definition did not match the older temporary-item detection heuristic.
• Added focused temp grant logging so test logs can show current temp/effective counts and the calculated target.

1.2.7 Temporary Item Storage Cleanup

• Removed the inaccessible Inventory.TempItemsStorage hook path.
• Avoids HookGen/protection-level build failures around RoR2's internal temp item storage type.

1.2.6 Pickup Path Compatibility

• Improved pickup grant handling so extra exponential stacks are added after normal pickup resolution when needed.
• Extra temporary stacks are granted through GiveItemTemp; permanent stacks continue using GiveItemPermanent.

1.2.3 HookGen Name Fix

• Fixed HookGen naming assumptions from earlier local builds.
• Removed stale overload-specific hook references that could fail on current generated MMHOOK assemblies.

1.2.1 Temporary Item Detection

• Improved detection for temporary/FoodTier-style items.
• Temporary items are checked before tierless/hidden filtering, so Affect Temporary Items = true can allow them even when Affect Tierless Items = false.
• Added debug logging for blocked/allowed temporary items when Enable Debug Logging = true.
