History of Arc Borne

'''Arc Borne''' is a 20-point triumph: complete the Crown of Sorrow raid with a fireteam made entirely of Arc subclasses. Void Borne and Solar Borne are the sibling triumphs.

== How to complete ==

• Every member must run an Arc subclass: Arcstrider (Hunter), Striker (Titan) or Stormcaller (Warlock).
• Do the whole raid without switching away from Arc.
• Bungie forum reports on a similar Arc raid triumph in Deep Stone Crypt say that the middle subclass tree sometimes failed to register while top or bottom worked. That was a different raid, so treat it as a possible bug, not a rule.
