How can Lifeforce gift to epics?

[dstokes7]

I was listening to Lux again, and it makes it very clear that Wingflare, Languish, and Cloudbreaker have immortality powers gifted to them by Lifeforce. That was how he persuaded them to serve him and how Wingflare survived the sonic gun blast. But in Steelheart, it is also made clear that gifter epics CAN'T give their abilities to other epics. That's why Megan couldn't use the tensors or the harmsway. So how is Lifeforce gifting his healing/immortality to other epics if gifters can't gift their powers to other epics?

Lifeforce is generally quite strange as far as epics go. His corruption is also very different from what we see in the original Reckoner's trilogy. As far as gifting, you'd think that if he was a normal gifter then he'd be providing his troops with the power to transfer their injuries to people they're touching, but instead they get the power to transfer their injuries to people Lifeforce is touching. As I said in a post years ago, other gifters act like a battery where they can give someone, say, 5% of their total power and then that slowly gets used up by the giftee until it fades away whereas Lifeforce acts more like a relay where people can use his power as if they were him. My point is just that he seems to be the exception to many rules, not just the one you mentioned. With this in mind, my conclusion is that he's so weird because of Deathrise. Unfortunately, we might never get any elaboration on what Deathrise is or how it interacted with Lifeforce's powers, so anything beyond that is mere speculation.
