How is the Cache of Uldir item level reward determined in World Of Warcraft?

Solution 1:

It's simple: Timewalking events (for dungeons in past expansions) are ALWAYS Normal for the latest raid, which is now Uldir and with patch 8.1 will change to the recently announced Siege of Zuldazar. the Mythic Dungeon event (for dungeons in the current expansion) is ALWAYS heroic for the latest raid. Items can still warforge (+5 or +10 itemlevels), titanforge (+15 or more itemlevels), gain a socket or a tertiary stat (speed, leech, indestructible or avoidance) in accordance with the rules for the item the cache gives you. Currently, there is no way to get a raid finder or mythic cache.
