Not working abilities?

[Robert Darkrage]

Just a side note, the +3 Viper's Nest Boost doesn't seem to work, I have compared the skill damage with other knives and at least to me the boost doesn't seem to work. Please move this if it belongs to another thread, otherwise, continue to report any suspect not working abilities.
Thank you!

I've noticed this for sailing as well; Full Sail, Ramming Speed, and Come About don't work for even half the duration it says it should. Hopefully they are working on a solution
