Throughout Drova, you can find shrines that request an item, but they don't specify what it is. Offering these items to the shrines will grant you a Mind +1 bonus. Pretty good if you ask me. This is also completely optional.
Most/all of these can be found in Act 1, but I obtained them in Act 4, near the end of the game, with no problem. Also note that these are NOT listed in any particular order.
Additionally, I'll mention which item they need, but not their exact location. The reason for this is that these are VERY common items that you find throughout your journey. Most of them you find in dungeons and ruins, so make sure to pick everything up.
