I found a quick and easy way to earn experience points in Chapter 5: Wygol Village. When you reach the graveyard part, block the two holes with the statues then on the third one break the wall in order to push the last statue out, leave it as it is and just kill the ghouls until you have enough exp to get the holy cross upgrade. This will help speed the process, by allowing you to kill faster and gain exp fairly quickly. You can keep killing the ghouls until you have max out everything on the combat cross. Also, sorry about the bad quality that you can't see how much exp points I got under a 1:34, but you gain roughly 400 exp points per wave of enemies. Within these 3 waves I earned about 1200 exp. Hope this helps everyone in wanting to max out everything or just getting a specific move fast!
EDIT: It seems someone has found a quicker way to gain exp through the butcher, but if you just recently got to this area and want to get some exp before moving on then try this method out.
