After running for a few Elite 5 and Heroic finally we have found the method how to easily beat the Cavern of veil with ease in Riders of Icarus. I would like to share this easy strategy with other players for your reference and discussion.
Teamspeak, skype, or discord is
party we require only 4 people: wizard, they are very good
guardian, reliable priest, and an assassin or another wizard. Everything
pre-boss is face-roll. Guardian grabs agro, wizard blows everything up, and
priest does whatever he does.
