Round table

My clanmate, Sir Tourist, wrote about Pandoras a long time ago.
The contents depend on the value of the object:
- If the defense strength is less than 5500, then it contains spells of level 1 or 5000 gold.
- If the defense strength is less than 6500, then it contains 5000 gold.
- If the defense strength is less than 7500, then it contains units of level 1 or spells of level 2.
- If the defense strength is less than 10000, then it contains 10,000 gold.
- If the defense strength is less than 11000, then it contains 10,000 experience points, creatures of level 2, and spells of level 3.
- If the defense strength is less than 13000, then it contains creatures of level 3 or 15,000 gold.
I have written many times about how to calculate the value.

Pandoras give creatures from one of the castles that are on the map.
The number of monsters of each type is fixed. For example, there are always 45 Gogs and 30 Magogs.
