No no she did not give Vali anything! She [and this is how her blessing ability worked on Vali], flowed a very tiny portion of her power into Vali's body where she increased his power to be on the same level as Issei's psuedo DxD form, then reeled her power back in her body. You would be saying Asia has Ophis' power then which is clearly not the case. The Blessing ability works in correspondence to what a person has an affinity for. For Vali it's power so the ability works in a different way in correspondence to him. For Asia, the way the blessing worked, was because Ophis is a dragon herself, she gave Asia a strong 'presence' within her that attracts strong dragons to take interest and trust her.
