Well, that’s one way to build. I just prefer offenses over set bonuses on Blaster. I use Barrier/inspirations/teammates for survival and don’t pursue defense bonuses at all. With that in mind, I would typically have 2 damage procs in Blaze, 3 in Blazing Bolt, and 5 in Char. Probably some in your secondary’s heavy hitter too. But, again, that’s if you can stand life without defense bonuses.
