Stealthy Thief Quests

Something that always kinda bugged me about the Thieves Guild in Daggerfall is that doing their quests rarely makes me feel like a sneaky thief. More often than not, their quests boil down to walking into a building, finding an item, and fighting whoever's guarding it, and it feels like my thief skills don't have any relevance to my success. So I decided to edit some of the vanilla Thieves Guild quests to make it so that the player's Stealth skill affects their outcome.

Quests changed:

The Qualifying Examination: Random chance (affected by your Stealth skill) that you won't be heard when entering the house, giving you 5-20 extra in-game minutes before you're discovered and the hostile mages start spawning.

Antique Ivory: Random chance (affected by your Stealth skill) that you won't be heard when entering the house, giving you 5-20 extra in-game minutes before you're discovered and the guards start spawning.

A temple Visit Random chance (affected by your Stealth skill) that you won't be seen when taking the item, causing the guardian not to spawn.

Valuable Artwork: Random chance (affected by your Stealth skill) that you won't be heard when entering the house, causing the guardian inside not to spawn.

Jewelry heist: Random chance (affected by your Stealth skill) that you won't be heard when entering the house, giving you 5-20 extra in-game minutes before you're discovered and the guard spawns.

The Noble's Jewelry: Random chance (affected by your Stealth skill) that you won't be heard when entering the palace, giving you 5-20 extra in-game minutes before you're discovered and the guards start spawning.

A Prized Item: Random chance (affected by your Stealth skill) that you won't be heard when entering the house, causing the guardian inside not to spawn.

Valuable Pages: Random chance (affected by your Stealth skill) that you won't be heard when entering the house, causing the guardian inside not to spawn.

A Prized Herb: Random chance (affected by your Stealth skill) that you won't be heard when entering the house, causing the guardian inside not to spawn.

The Rich Merchant: Random chance (affected by your Stealth skill) that you won't be heard when entering the store, causing the guardian inside not to spawn.

A Tresured Potion: Random chance (affected by your Stealth skill) that you won't be heard when entering the apothecary, causing the guardian inside not to spawn.

The way your Stealth skill affects the chances previously mentioned is the following:

0-9: You will always get caught

10-19: 10% chance of not getting caught

20-29: 20% chance of not getting caught

30-39: 30% chance of not getting caught

40-49: 40% chance of not getting caught

50-59: 50% chance of not getting caught

60-69: 60% chance of not getting cau
