I was playing the map Double Confrontation yesterday (ToTE) and there was an Inferno hero who was jumping on and off boats and continuing inland or out to sea without needing to stop for a day. I was curious about how he could do this and looked over the inferno talents but couldn't really see anything that should let him do this.

Is this a bug, or a talent I missed, or an artifact?

There is a logistics skill called snatch that allows this.

Wow, I assumed it affected picking up objects only, cheers for the heads up and lesson in reading :P
