Currently, Blood School is a fairly weak (if not the weakest) school because it doesn't have infinite scaling (because you can't stack Blood Corruption infinitely) and it also has defensive issues. Therefore, it would be nice to make its survivability a little easier, for example: give Blood Corruption a small amount(like 1-2% of ordinary tech) of barrier per stack before each tech

You could make that a tech you get around or after the one that makes blood echoes off any blood art. Especially since that's finally when you can start getting your feet under you for the equally volatile and sorta mid shadow stuff you pull outta the mines.
