Tough Guy requires you to reach Wave 15 on Survival or Pure Strategy on Hard or higher difficulty.
Some players have reported that they do not get credit for the achievement unless they let their Eternia Crystal die after wave 15.
If you reach wave 15 on someone elses game, you can sometimes not get this achievement. Sometimes this can be fixed by returning to your own tavern.
