Question on Getting the Oro Ornament (when it come to consoles)

[(PSN)A_SimpleName]

Do I need to do all Tier (i.e. Sigil, Upgrade packs, and then Oro) or can I just do the last Tier (Oro) when it become available? My sanity will be very appreciated. Please refrain from posting your opinion on the Event. I just want to know the answer and not turn this into what other related thread has devolve into. Thank you in advance.

It doesn't work in tiers, if you only want the Oro then only go for the Oro.

You can ignore the other 2 which reward different things. Just go for the one which reward the oro.
