Accolades are awarded to you at the end of a match for meeting certain criteria during the match, such as getting the first kill, the most kills, the first to destroy a tower, destroyed the most towers, etc.
If you want to just farm the achievement in a game (not really necessary~) you can do something like this for the following accolades.
Ignore the bad guys, rush to one of the Shrines when the match starts (3-Lane preferred)
Power Hungry and Arcane will unlock if you're the first to capture a Shrine, and capture the most shrines in the game, so spend the game bouncing between shrines. Keep using your command ability as well to get General for using the most commands. Depending on how you're running around goes you may get Immortal (Longest Life), Cautious (Fewest Kills), Wounded (Received Least Healing), Ranger (Most Distance Traveled), and Survivalist (Fewest Deaths). Obviously quite a few accolades to unlock by basically doing nothing but run in circles, and get this achievement..and progress toward Notches in the Axe.
