It boosts your NP overcharge. Say I have Mash NP and Arturia NP ready to go, if I select Mash NP first and Arturia NP second then the Arturia NP gets an overcharge of 200%.

NP chains grant every successive Noble Phantasm card in a command queue an extra 100% NP charge.
First card will not receive a bonus
Second card will receive 100% extra NP charge
Third card will receive 200% extra NP charge.
NP chains only occur if the Noble Phantasms are lined up one after the other. Selecting a normal command card between two Noble Phantasms does not active an NP chain.
