I can't provide you with the information Sophicles stated but she has resurrected herself in Trial of Magneto and has said she that death cannot claim her.
Now there are a few more scenes scattered throughout the series that depict the process of her being reborn. In this instance it was not instant so since you brought up a 10-count that would indeed be an issue.
There is no way of telling if what you saying would even kill her at this point though. She absorbed Chthon and took his power in Darkhold Omega and we haven't seen anything more since then but even Doom who was angry at her for doing that didn't dare to confront her in person about it. That can be interpreted multiple ways.
