Armiger prepared for each death (4,6)
I believe the answer is:
grim reaper
'death' is the definition.
(grim reaper is a kind of death)
'armiger prepared for each' is the wordplay.
'prepared' indicates an anagram.
'for each' becomes 'per' (I've seen this in another clue).
'armiger' with letters rearranged gives 'grimrea'.
'grimrea'+'per'='GRIM REAPER'
(Other definitions for grim reaper that I've seen before include "Name for death" , "Death personified as Old Father Time" , "Death in person" , "which represents curtains?" .)
