Nad 20s and taming creatures should end combat!

Since in friends and fables franz has a little trouble by the word of “Taming” Sooo when you tame a beasts should combat just end like you tamed the beasts you were facing? Like by example: You faces a dragon you rolled then approach the dragon and just roll pretty good like a nad 20! Should combat just end? With the beast now loyal and friendly to the player? Since i HAD to deleted a campaign but his would be fun and easier than just well slaying beasts! And also to make sure franz know that naturals 20s should just succeed (I am still a new player but i know you can tamed creatures!).
