🎯 Tips & Tricks
If you use East Scarp 3.0, do NOT install this standalone version — it will conflict.
Make sure you have SMAPI installed, as most Stardew Valley mods require it to run.
Place the mod folder in your Stardew Valley 'Mods' directory, then launch the game with SMAPI.

⚠️ Common Mistakes
- Installing multiple mods that modify the same files without checking compatibility
👍 Pros
- Huge community trust with 3,913 endorsements and nearly 300k downloads.
- Standalone version means you don't need East Scarp to enjoy this character.
- Recently updated (Dec 2025) so likely compatible with current game versions.
👎 Cons
- Explicit warning not to install alongside East Scarp 3.0 — potential conflict if you use that mod.
- No detailed feature list provided, so you'll have to discover what Jasper offers in-game.
- Only one NPC added — if you're looking for a larger content pack, this might feel limited.
