Worthwhile Restoration
Worthwhile Restoration is a passive skill that awards 3 
after restoring Mana. The restored mana doesn't have to be all at once, and works with mana regeneration as well as foods that restore mana. After 2 or 3 points invested in this skill, 4 gold is awarded instead of 3, though this isn't mentioned in the tooltip.
This is a multiplayer global skill, which does not stack if more than one player puts points into the skill and will be applied to all players in that world. Global skills will take the highest value of all players on that world. If one player has three points into this skill, while another has one point the game will apply the three point bonus to that world.
