When you play a Lesser Noble, you may choose either of these two effects (but not both).
You may lower the cost to solve a Problem by 2 Food until the end of the turn. This option may be canceled by a Hazekiller or similar game effect.
You may discard the Lesser Noble along with another Personality card from your hand to remove 1 Ruined token from any card or sheet in play. The formerly ruined resource may then be collected normally. This option may not be canceled in any way, even with a Hazekiller card
