are they relics randomly chosen or is their a way to know which pet to choose?

If you're talking about the forgotten tomb seals, you should read this thread: https://www.sylestia.com/forums/?thread=622&page=1


You will need to translate the text (someone has done that in the thread), in order to know which seal it's asking for, then you can figure which pet to use.

Each seal requires a different pet with a certain amount of the right stat in order to be activated. To know which seal requires which stat, browse through the above thread to see what other players have discussed. We don't know for sure the exact amount of stat needed, but generally try to use pets with all their stat points placed in that one stat.


You won't know for sure if your pet activated the seal, until you've reached the 4th seal, and then, only if all the seals were activated. Then, the last seal will light up.
