Bonus Effects of unlockable Staves and Robes

The ingame description of Staves and Robes isn't very accurate and sometimes missleading.
For example: Bonus to Water doesn't have any effect using Staves even if it's in the description.

With Version 1.1.0.0 they fixed bonuses on Earth and Shield spells.

This list doesn't include any monster drops.
