Sariel did not need to reward Rudra anymore than he had already did. But the angel was soft by nature and gauged that the biggest flaw Rudra had in his fighting was not his technique of his skill , but his speed.
Compared to tier 6 beings he was incredibly slow and his heart bled at that thought.
Without meaningful speed Rudra was never going to give Lucifer a challenge, hence he took off his own boots and decided to gift them to Rudra.
Sariel was a little impressed with Rudra by the end and decided to bless the demi-god with an artifact that he thought would help carry him a long way.
The angel said " Here , a parting gift for you , it will give you a slight advantage that you desperately need to fight tier 6 opponents , although it won't be nearly enough to catch upto big brother Lucifer, maybe you will just die slower if you have this facing him ".
