There are 3 different levels of datacrons: 10, 25, and 50. They level 10 datacrons will reward you with +2 of either aim, presence, cunning, strength, willpower, or endurance; or a matrix shard. The level 25 datacrons will reward +3 of the attribute, and the level 50 will reward +4. They matrix shards can be used to craft high level relics, and can be assembled and broken down.
