SWING_DAMAGE / SWING_DAMAGE_LANDED

SWING_DAMAGE follows the melee swing timer and is always sent. When Advanced Combat Logging is turned on, SWING_DAMAGE_LANDED is also sent which occurs when the actual damage of the melee attack is applied to the target (optionally following batch windows) and includes extra information about the target unit, while extra information about the source unit is added to SWING_DAMAGE.

SPELL_DAMAGE / RANGE_DAMAGE

This event is sent when a spell actually deals damage to a target as opposed to the spell cast succeeding via SPELL_CAST_SUCCESS. Resource checks/hit checks/damage calculations/etc. for a spell cast are done immediately and are reported via SPELL_CAST_SUCCESS right as the cast ends, and if the game determines that the outcome of the cast should deal damage then the damage is delayed until the next batch update and the time delta between this event and the preceding SPELL_CAST_SUCCESS that caused it can tell us how much the damage was delayed because of spell batching. If advanced combat logging is enabled extra information is provided for the target of the spell.
