The reason your attributes are red in Oblivion is because they have been damaged or are being actively drained. This can happen due to diseases, poisons, curses, or attacks from certain enemies like the Drammora in Oblivion gates. The red color indicates that the affected attribute is below its normal level. These attribute damages do not automatically go away and can accumulate. To fix this, you can:
- Pray at a chapel altar in any town, which will restore your attributes.
- Use restoration spells or scrolls that specifically restore attributes.
- Use alchemy potions designed to restore damaged attributes.
- Cure any diseases if present, as diseases can cause attribute drain.
If you notice attributes in red without active effects or diseases, it is likely permanent damage that requires one of the above methods to repair. Sometimes carrying certain cursed items can also lower stats, so removing such items can help. In summary, red attributes mean damage or drain that must be actively restored through gameplay means.
