Quote from sakraycore;291434:
it looks pretty good but how easy/hard is it to get the trinity staff? How much will it be in the housing shops?
Well the same person who posted the video said in her comment...
1. Trinity clothing sets are rare reward from the theatre missions. However Korean and Japanese mabi had an event giving the staff and other newcoming stuff including the sets, I got my set gears throuhgh that event. 2. read my past comment for more information. 3. Theatre missions are almost same as the shadow missions. You can redo.
I found the staff is not so rare, got 2 staves in 30 theatre mission trial
The missions it comes from is request from the new kind hard, and this is the summary of the event that gave them.
3 emissionaries(the NPCs saying they were from NA, KR and CN mabi) appeared near the Dunbarton admin office and each of them gave a player character a gift per day. Logged in as every my characters, talked to 3 NPCs, received 3 gifts. We repeated it during an event period. A trinity staff was a one of the rare gifts.
So for those of us with many characters and many accounts you can farm this event everyday for rewards. This is the reward list that they had on the JP Mabi wiki. I used google translate so they aren't translated perfectly but could easily be figured out.
