With the challenge mode guaranteeing 320 items getting a 320 character is alot more achievable than the pure RNG of before. Each time I have completed a Challenge my character has raised a light lvl. Sitting at 317 currently, If challenge Oryx gives out either a 320 primary, helmet or boots i'll popup a level again. Only run one character on the raids once a week, have a second character that is 313 purely from infusing my primary characters leftovers.
