This has been asked so many times it's actually getting silly.
Even more annoyingly, is that you spelt blood with so many "o"s that even if I give you the answer, no-one else will find it when they search blood.
But, anyway.
Open the characters FPE file in the entity bank and increase the "decalmax" value from 2 to say....30. The Bigger the number the more blood that will be created.
Bear in mind that for it to work, you will need to edit the FPE file and then delete the character's corresponding BIN and DBO files. And no, I'm not explaining what they are.
