==========
it seems that the bardsong synergies with other classes - that is, for example, rogue levels being added to bardsong levels when using pilfering poem for example - simply does not work.
Steps to reproduce
----------------------------
be a bard with a dip in something else. try using a bardsong that synergises with that other class
Expected result
-----------------------
actual synergy
Actual result
-------------------
no synergy
