Board Game Arena

Hi folks,
I miss an explanation/rule concerning points counting at the end of the game.

Using the "bestiary", i brought back 3 dragons in my table: the 2 first gave me 3 points (1 for the dragon card, 2 for bestiary card), the last one 4 (1 for the dragon card, 3 for the bestiary card)?
I have no animal in my table.

The counter indicates 7 points for the bestiary card at the end of the game?

Can we earn points with dragon attacking as well?
Thanks for your explanation.
Regards,

Hi. There is an artifacts, the Sea Serpent, that count both as a dragon Ans an animal ans so worth 4 Victory points with the bestiary
