I've been doing some testing. Ill add a post with details later but in general, the factors that effect your stealth chance in game make intuitive "real world" sense. Unfortunately the interaction between type of armor, piece of armor (gloves, leggings, etc), and stealth skill make for a huge list of possible combinations to test out:
- The type of armor you wear increases steathling difficulty as expected (From easiest to hardest: medable armor, studded armor, ring armor, chain armor, plate armor)
- The more pieces of non medable armor you wear the greater the difficulty to stealth (at 120 stealth you have 0% chance to stealth in all nonmedable studded armor, but you will never fail with only 1 piece of nonmedable studded armor)
- "Bigger" pieces of armor seem to decrease your chance to stealth more than "smaller" pieces of armor of the same type. For example: A studded tunic lowers your chance to stealth A LOT more than studded gloves.
- Non Medable tunics make a HUGE difference in your chance to stealth.
