## About The Pull Request https://github.com/user-attachments/assets/173c1753-3da4-4180-80ea-eb49d19e7b2f Purely visual. Pulling someone from an IV drip is dangerous so it's nice to make it more clear than the current very small appearance change that doesn't give you any more information than that *someone* is connected. If you review tell me on Discord bc I don't check GitHub ## Changelog 🆑 qol: IV drips now create a beam from their spout to your body, and will visually pull you closer. /🆑
