Season 2 of Diablo III included some Achievements that were only obtainable for players who were playing a Seasonal character while Season 2 was active. Earning some of them was fairly easy.
All a player had to do was earn a certain amount of Seasonal Achievement points. It didn’t really matter which Achievements they happened to be.
The “Feats of Strength Achievements” in Season 2 are not the same as the ones that appeared during Season 1. They have a few things in common, though. In both Seasons, this group of Achievement unlocked special banner shapes, patterns, accents, and sigils. The main difference is in the names of the Achievements. Players who earn them all can show off by changing their banner to show some of what they accomplished in Season 2.
This one unlocks a new Banner Shape.
This is what the Banner looks like with the special Season 2 rewards. Obviously, you can change the colors around to suit your aesthetic tastes. I picked the red background because I got tired of the green one I had been using since I earned the Season 1 special Banner rewards.
Those that earn this Achievement unlock the two “transmog” items that are only available in Season 2. I was able to unlock the two “transmog” items that were obtainable during Season 1. Right now, I’ve got four of the six piece “transmog set”. (The last two pieces will become available in Season 3).
Here is Dusk the Demon Hunter wearing the head and shoulder transmogs that players could earn by getting a Seasonal character to Level 70 in Season 1. He is also wearing the legs and feet transmogs that players could earn by getting a Seasonal character to Level 70 in Season 2. I chose to dye everything blue.
