Potion Splasher

Potion Splasher

A lightweight client-side mod for competitive PvP: define presets of splash potions, bind each one to its own key, and throw the whole set with a single press — no fumbling through your inventory mid-fight.

How it works

Build a preset by picking which potion effects you want (searchable list, any combination, duplicates allowed) — the mod automatically figures out which hotbar slots to use, filling in from slot 9 leftward (1 potion → slot 9, 2 → slots 8–9, 3 → slots 7–9, and so on, up to the whole bar).

Press that preset’s key and the mod:

Finds a matching potion for each slot anywhere in your inventory
Temporarily swaps it into the right hotbar slot
Throws it
Puts whatever was originally in that slot back — exactly where it was

If a potion type isn’t in your inventory, that throw is skipped with a chat notice instead of launching the wrong item.

Features

Unlimited presets — name them, edit them, delete them, each with its own independent keybind
Searchable potion picker — type to filter through all standard splash potion effects (including tier II / extended variants)
Conflict-safe keybinding — the mod won’t let two presets share the same key
Configurable throw delay — tune the spacing between each potion in a sequence
Zero inventory management — your original hotbar items are always restored after the sequence finishes
Clean in-game config screen, no external config editing required

A note on fair use

This is a pure automation/macro mod — it only performs actions you could already do manually (switching hotbar slots and throwing), just faster and more reliably. It doesn’t read hidden information, doesn’t touch other players’ data, and doesn’t modify anything server-side beyond normal inventory clicks and item use. That said, some competitive servers explicitly disallow macros or auto-clickers in their rules, even for actions a player could do by hand. Check the rules of wherever you plan to use this before you do.
