I know this question may be years out of date but the Jellyfish Cape can be recharged to succeed at a con/fort check to defeat a bane with the aquatic trait. Does this work only against the few barriers that are aquatic AND have a constitution/fortitude check to defeat? What if you are hit with man overboard which requires a con/fort check to banish after you fail the initial check to defeat? Does it work against BYA con/fort checks from aquatic monsters?
On a related note about BYA checks on banes, you can't use the eye patch on them because they aren't checks to defeat?
