That's because you'll be putting Holy Burst on one of your ToD rings and Holy + Holy Burst stack (or they're supposed to, in the case of Cannith Crafted Handwraps).
Lately, I've taken it wearing my Epic Wraps of Endless Light from the Mabar event as my devil boss beaters. Shintao Monk allows for Silver/Cold Iron DR-bypass and I already have Holy Burst on a ToD ring, so I still completely break DR (although I do have a set of loot-gen +1 Holy of Greater Evil Outsider Bane handwraps with Risia Icy Burst on them).
