How high is Issei's potential?

1. Has Boosted Gear Mid-Tier Longinus (with a portion of Albion's power) - When mastered can kill a God/Satan

2. Has the flesh of Great Red

3. Has the power of Ophis

4. Ascalon - One of the 4 Holy Swords made be God

5. As stated below - Unknown conection to Balor, God inside "Forbidden Balor View"

If Issei mastered all of these excluding number 5, how powerful would/could he be?
