We have two tags that appear to me to be synonyms, and both have been around for a while:
status-effects × 37 questions†
(created Apr 23, 2014)
Status effects are game keywords which affect a creature's status, e.g. unconscious, weakened, on fire, poisoned.
conditions × 61 questions†
(created Oct 1, 2014)
A condition suffered by a creature, typically negative and as a result of an enemy's actions during combat.

Is there any reason to not make one a synonym of the other? If we don't need both, which should we keep?
