QuestMod

A BepInEx mod for Hollow Knight: Silksong that gives you full control over the quest (wish) system — unlock, accept, complete, rewind, and tweak quest targets from an in-game GUI.

Features

• Quest State Control — Accept, complete, un-accept, or un-complete any quest
• Chain Quest Grouping — Multi-step quest chains (Main Story, Citadel, etc.) collapsed into single rows with ◀/▶ step navigation
• Per-Save "All Quests" Mode — Unlock all quests on boards and NPCs for the current save (resets on title screen)
• Target Count Overrides — Edit quest completion targets (e.g. lower Silver Bells from 8 → 3) with per-target sliders, QoL presets, and a multiplier slider
• Checklist Toggles — Toggle individual sub-targets for multi-target quests (Grand Gate bellshrines, Flea Games, etc.)
• Silk & Soul Tab — Edit threshold requirements, quest point values, and track completion progress
• Mass Operations — Accept All / Complete All with undo support (gated behind config)
• Guaranteed Silver Bells — Force every bell drop to be a Silver Bell (overrides the 75/25 split)
• Quest Item Protection — Prevent delivery quest items from being destroyed by enemy attacks
• Act 3 Toggle — Manually toggle Black Thread World state
• Data-Driven — Quest registry, max caps, chains, and S&S data all loaded from QuestCapabilities.json
