• a random equippable item
  
• an ultimate ability book
  
• a secondary ability scroll
  
• a random weapon

These are the most common altars, and take the form of statues with small offering bowls. They are easily accessible and usually appear along the peripheral walls of the room. They will accept a single coin in exchange for a +1 boost to the character's stat, dependent on the statue. Often times blessing altars can be difficult to spot; they tend to blend into their surroundings, both in color and in geometry. Scanning the peripheral walls of the room is a good start.
