I have a system for DnD that I want to work out. The systems goal is to make more use of the tool proficiencies in DnD. The goal would be a system that you can use for 5 to 10 minutes at the start of the session and should therefore not use up too much time.
The system is about a guild. Whenever someone of the group creates a character, they will become a member of the guild. If the character is not in use/not played with in the adventure, it will be able to work in the guild. The players will be able to construct guild hall rooms for the tools e.g. a kitchen for cooks utensils proficiency, where the characters can work.
Now for my problem. The rooms will have 2 levels. I want for the rooms on first level to have a basic function and on second level to have more powerful functions.
That being said, this guid system should not generate things that are too powerful as to keep the adventuring the main focus of the game and as mentioned before, it should not take up too much time, so many individual tasks to work through are not optimal.
Could you give me items and functions for level 1 and 2 of the Poisoner's Kit room including descriptions?

Please give me a list of possible created items (can be magical but dont need to be) or alternatively activities that the player characters can make/do and functions including descriptions for both level 1 and 2 of the Poisoner room. Please give specifc examples for items on both room levels.
