One of the more frequently asked for bits of information we get asked is..
"How many npc's must I kill before achieving my next rank?"
Well for the most part it's fairly similar, but there are some exceptions to the rule.. The charts to follow will show the current NPC kills needed to reach certain ranks.
On the left column of the chart will be the rank you'll achieve given you reach the number of NPC kills indicated from the right column of the chart.
**I'm already aware of the mistake in the Human rankings regarding the mix-up between Private and Corporal, that'll be fixed with the next reset.**
With regards to the Hollow/Arrancar Rankings.. if you stay a non-arrancarized (you haven't removed your hollow mask) hollow you will only be able to rank up to the Vasto Lorde level. That said, if you reach the Vasto Lorde level and then Arrancarize you'll receive a bigger boost when you do go through the process. After you Arrancarize you'll be able to continue ranking up as per the remaining ranks on the chart.
