Monk with an FBSS - Peacebringer or Imbued Fighter's Staff?

[Kayso]

PB>IFS at level ~43, but the difference is only 1% at level 46 and only 3% at 60. So if you are choosing it as a tanking weapon in groups, consider the IFS for weight and taking less damage from damage shields and ripostes.

The Adamantite Club + SoS combo does more damage than either of these starting in the low-mid 30s.

And though you didn't ask, the Adamantite Club + SoS combo becomes more DPS than SoS x2 right about your level.
