SPOILER 2.0 Light Bender Party Trick

Ok so, I was doing the lava spring quest on a lower lvl, as ya do. When I walked up to the healer potion guy, and saw this.

it made me think,
"oh hey, i wonder does this work with Light Bender"
so i hopped on beta and brought my 106 over to the healer merchant.
and low and behold.

(the 4th orb is hidden by my task bar XD)
you can solo 4 spinny orb, without using the new spell or any other players, do this just before a battle, (about 3 pots were used to get this effect)
now imagine, this again, but a whole group, instant invulnerability. Or so i guess, i haven't tested with more then one other player.
idk how viable this is in a fight XD, but atleast its a neat party trick.
