Well I know this might make people overpowered but I was wondering if like sennin we could have the curse mark as well just a suggestion though

Please refrain from making the same topic twice.

To address your point, both me and Sinister considered the curse mark option before we even opened the new version of the site. Of course, as you can see, we decided not to have such a feature. We encourage creativity by not giving people all these S rank abilities off the bat, and Sage mode did in fact differ slightly from the original canon version from the series; and even if we were to open up curse marks, which we probably won't, there'd be quite a few requirements.

Also, we don't want to end up over powering characters to the point they're unbeatable. We want to keep a level playing field here, for now, at least.

Well looks like WB handled that one
