2 Similar bugs are described below. Additional details and notes are listed at the bottom in order to assist in reproduction of these issues.
Note: My play-through initiated before the 1.3 patch. I've read that companion attributes have changed since the patch if you start a new character. I have not tested this bug with the new companion attributes to see if that might have changed the way this behaved but I suspect the issue is still prevalent there as well.
If you have any questions, Please let me know!
Bug 1
Version: 1.3
Platform: Steam
Date: 4/4/2015
Description:
When swapping between two items in different slots that give a bonus to the same attribute, permanent attribute loss can occur.
Reproduction Items:
Kana's Turban: +1 Intelligence
Drinking Horn of Moderation +2 Intelligence
Reproduction Steps:
Equip Drinking Horn of Moderation (Int goes up by 2) Equip Kana's Turban (Int goes down by 1, Turban overrides the Horn's greater bonus) Remove Kana's Turban (Int goes down by 1) Remove Drinking Horn of Moderation (Int goes down by 2)
Net Loss: 2 Intelligence
When removing the Kana's Turban followed by removing the Horn of Moderation, a permanent 1 point stat loss occurs. Repeating this process can bring the intelligence stat down repeatedly.
Note: As I am playing a Godlike character, I reproduced the steps above on the Kana
Bug 2
Version: 1.3
Platform: Steam
Date: 4/4/2015
Note: This bug is nearly identical to the first with one minor exception. See reproduction steps.
Description:
When wearing two items with similar attribute bonus', When swapping between two items in different slots that give an a bonus to the same attribute, permanent attribute loss can occur.
Reproduction Steps:
Equip Drinking Horn of Moderation (Int goes up by 2) Equip Kana's Turban (Int goes down by 1, Turban overrides the Horn's greater bonus) Remove Kana's Turban (Int goes down by 1) (Repeat steps 3 & 4: Each repetition drops Intelligence by 2, 1 Int for each step) Remove Drinking Horn of Moderation (Int goes down by 2)
Temporary work around: Do not equip items that give a similar stat boost. First remove the stat boosting item and then equip the new item.
Additional Details:
When using Rundyl's Finery and Drinking Horn of Moderation, Attribute loss occurs as well. In bug 2 version, Attribute loss only occurs when removing one of the 2 items. At that time, 2 Attribute points are lost. Both items give 2 attribute points.
Using 2 +1 items does not cause this to reproduce.
Confirmed Bugs 1 and 2 also occur on Eder.
Using Rundly's Finery and Drinking Horn of Moderation on Durance, I was only able to get Bug 2 to reproduce when I unequipped Rundyl's Finery but did not actually place the item back into the inventory. In order to reproduce this, simply drag the item from the character with the mouse and then drop the item back onto the chest piece without placing the item back into the inventory.
I have been entirely unable to reproduce this issue with Lilith's Shawl (+3 perception) and Spider Fingers (+ 1 perception). It appears this may require the inclusion of at least 1 +2 Item.
