How can I check if a bazaar character has collected the reward from the Soul War quest?

Question

My friend placed his character on the bazaar and only then we realised that it does not show in the list of completed quests "Soul War" quest even though he already killed Groshnar's Megalomania and collected his reward. This can give the impression to the people that the reward is still available on this char. 

How else I could check if a bazaar character has collected the reward from the Soul War quest?

Example of the char:

Answer 1

The best way is by checking the outfits- if it has Revenant(base) outfit. You will receive Revenant outfit after defeating Groshnar's Megalomania.

What was the answer to the question that was different. Yes base outfit after killing Groshnar's Megalomania does that answer the question? The question was whether it is possible to find out that the character received the item after killing Groshnar's Megalomania we have a super outfit but it is not known whether the item received or not..... Damnn....
