I loved the suggestion, I just didn't intend for Dragon Sodality to hunt anything other than well, dragons. Lol.

Ah! Another good question :)
I was thinking that per character no more than two of the listed abilities can be chosen. Choosing one of the abilities will mean that the character could (potentially?) be less powerful than those who have two. Though a single one will be easier to control.

As for limitations to the abilities, I guess we can leave them up to common sense. However, I will mention that each ability will possibly be unique to each slayer. For example strength is the ability to lift great weights, but it could also be the ability to have impenetrable/steel like skin, or something like a shockwave clap etc.
