I'm sure you wouldn't abuse it and have limits in mind, but I don't see how the sheet itself follows t-1 limits as we know it and here's why (in my opinion). If I wanted to be a jerk I don't see why I couldn't destroy everything in existence with dark lightning in one massive blast of lightning all around me. The light strain is likely what stops him from doing so, which is where you have to play responsibly and go on the honor system, which is unavoidable to an extent on such high power. But if light strain is for, say, planet sized attacks, the sheet still makes it sound like he could kill anything and everything in that radius, gods or what have you, which they could only not be destroyed by not getting hit at all, somehow dodging any number of lightning bolts he sends out. Blocking is impossible because he destroys anything it hits.

I'm basing this strictly on the sheet without outside context. If gods and higher level aren't instantly obliterated then that needs to be added into the sheet to fit your vision of his power under these rules.
