Ahh how many talents for Rank 1?Are you asking how many tokens we got for killing the final boss?
If so, you get the same regardless. The amount of shit you get is only affected by your actual point ranking, you just get 2-3 extra goodies from the boss by actually killing it. We have him down pretty well now and because we have an archer with double slow we usually kill him with 1:00-1:20~ time left and before he can even reach the dragon. Unfortunately that just gives us extra points and nothing extra that we can see. Our highest so far is 211k, still 29k off from rank 1 which is the only way to increase your talent yield.
