Overall, it results in characters that are a bit stronger and more skilled than normal, by-the-book PCs, but not overly so. This is the method of character generation I have been using in my Neverwinter Nights D&D "cloud" campaign.
6d10 (initial) -> 12d10 (doubled from Crit) 12d10 -> 120 (Maxed from overchannel) 120 -> 240 (from grace cleric’s channel divinity) And the last 5 came from the Wizards 10th level evocation ability. For wizards and sorcerers, that ability is called Hematurgy. The last cherry on top was the Wizard using Overchannel. All four blood magic subclasses for the casters have some variant of their main blood magic ability, however, regardless of their focus.
