This information is somewhat out of date.
The gift of the GODS, not Goods , is the reward given to the kingdom winning the event called kingdom v kingdom revenge.
The table refers to only two invaders that at the time of the post had ceased to be regular features on the global map.
This is no longer the case, they appear now mostly, if now not exclusively, as just 24 hr invaders in rotation with the other regular game invaders.
The materials mentioned are only to be found and only with luck, from yielding from the special fast L.7 tiles.
They are not extra payment, there are no levels, and they are not listed in order of strength and there are no creatures to attack
If by levels you mean from simple to legendary there is no guarantee on the quality of anything that drops from any tile , there isn't even a guarantee that you will get any item.If you want these items you need to attack the specific invaders themselves, the relevant composite Uber, or buy from the clan store.
