salvific
Able or intending to provide salvation or redemption.
Less well recognized, however, is the central role played in much of early medieval Pure Land Buddhism by deathbed practices and accompanying beliefs about the radical salvific power of one's last nenbutsu, whether understood as the contemplation of the Buddha Amitābha (or Amitāyus, Jpn. Amida) or the invocation of his name.
Where it comes from
From Late Latin salvificus, from Latin salvus (“saved, safe”) + facio (“make”).
