[Known] Multiple specialization tooltips are missing descriptions

Camouflage: on this tooptip, it says "Subterfuge Specialization" and then no explanation as to what it does.


Body slam - specializiation apparently increase the stun duration of body slam, but it does not say this on the tooltip.


Knight grace - not sure what this means "Heavy armor specialization adds a heavy armor specialization buff for 30 seconds" - does this mean that for 30 seconds my specialization raises to a higher level? If so, i could see no evidence that it was actully adding this buff.



Animal Charm - no buff for specialization shown on tool tip

 

Bug #: 56890, thank you!
