Downranking described the usage of spell ranks lower than the highest one in order to increase damage or healing per mana spent, or for the use of a secondary, rank-independent effect, in trade for a lower amount of damage or healing. For healers, this was sometimes necessary to prevent overhealing. Mana reservation was the desired aim. In most circumstances, downranking is no longer a viable tactic. In addition to voluntary downranking, when a buff spell is cast on a character whose level is too low to receive that buff, the character will receive a downranked version of the buff instead.
