Features

  • Fertilize plants (crops, trees) and pickables (berries, mushrooms, flowers) to make them grow or respawn faster, using items from a configurable fertilizer list.
  • Vines can also be fertilized, after which their pickable berries can also be fertilized, though it should be noted this is a bit finnicky and works best with fresh vines that were just grown rather than preexisting vines.
  • By default, the fertilizer list allows using either 3 Ancient Seeds (after Eikthyr has been defeated) or 1 Ymir Flesh (after The Elder has been defeated).
  • If multiple fertilizers are in inventory, consumption priority is given based on list order: make sure to position less valuable fertilizers before more valuable ones in the list.
  • By default, remaining time is reduced by 100% when fertilizing, meaning the effect is instantaneous, but this percentage can also be configured to a lower value. In this mode, a single plant / pickable can be fertilized multiple times with diminishing returns (but not more than once with the same fertilizer).
  • Translations available: English, French. New languages can be added easily (see below for details).

But why?

Instant Fertilizer™ aims to address the annoyances around initially setting up a farm: the first few Carrot seeds, Turnip seeds, and Onion seeds you find in the wild can be quickly cycled with fertilizers in order to speed up getting to a sustainable state.

To achieve that, the default configuration aims to give a purpose to niche items with little use in vanilla by:

  • Adding a new resource sink for Ancient Seeds, offering:
  • An interesting choice in early game between using your first few Ancient Seeds to set up your first Carrot farm or stocking up to summon The Elder.
  • An incentive in mid game / early late game to keep farming Ancient Seeds to set up your first Turnip or Onion farms.
  • Adding a new resource sink for Coins via Ymir Flesh, offering an interesting choice in mid game / early late game between spending your Coins on fertilizers or stocking up to buy expensive Eggs.

Compatibility

With vanilla clients / clients not using the mod

Plants and pickables are managed by the current zone owner (usually the first person to enter a zone), however Instant Fertilizer™ claims ownership of any plant or pickable on fertilizing.

It should thus work transparently with all clients, regardless of if they use the mod or not: the fertilized plant or pickable will grow or respawn instantaneously from their point of view as well (which might make you look suspicious if they're unaware).

With other mods

Instant Fertilizer™ hooks onto the Pickable, Vine, and Plant components and should work transparently with all mods, including those that add new plants or pickables.

In particular, Instant Fertilizer™ is explicitly made to be compatible with PlantEverything and Seasons.

Feel free to report any issue you find.

Install & use Install: BepInEx plugin

  1. The archive from playbuff is the mod itself — usually a BepInEx plugin (a .dll or a plugin folder once unzipped).
  2. Recommended: use a community mod manager (such as r2modman) — pick this game, import the mod, and the manager sets up BepInEx and its dependencies for you.
  3. Manual route: install the BepInEx loader in the game folder, then drop the unzipped .dll or plugin folder into BepInEx/plugins/.
  4. Launch the game — the BepInEx console logs every plugin it loads; seeing this mod in the log means it is installed.

Mods with listed dependencies need those installed too, or they will not load. Options are usually changed in-game or in the plugin's config file. In multiplayer, the host and every client need the same mods installed.

Dependencies

Install these first, or the mod will not work:
