Askar feet are -2% PDT.
For random cleaving, I've also used the lowly Earth Staff, in full -PDT/defense gear backed by MAB atmas (Ultimate etc) and used Cataclysm (average ~1000-1200, not as good as Fell Cleave, and not useful with Mighty Strikes, but not terrible). It takes a bit of the load off the healer(s) and is handy for amber light if you want it.
