Mystra's Blessing | Baldurs Gate 3 Wiki

Not sure if bugged but the mystra blessing buff remains even if you break concentration on the original bless you cast, so this is a good way to have bless up on your characters permanently. Still think whispering promise is more convenient tho, especially if you can cast mass healing word

I was doing some tests with this in conjunction with standard bless and whispering promise ring. The whispering promise 2 turn "bless" on heal does not trigger this buff, but spell slot bless lv1 and lv2 does (i dont have any levels higher than that right now). Mystras blessing stays on after ending bless concentration. I cant stack regular bless with whispering promise bless, but if i end regular bless then i can trigger whispering promise bless normally while mystras blessing is still on. Sorc extend spell only affects the duration of a standard bless spell and not the duration of mysrtas blessing or whispering promise

If you cast bless while wearing the staff the targets get bless as well as mythras blessing. Mythras blessing only gives 1d4 to spell attack rolls, nothing else. Bless gives 1d4 to attack rolls (melee/ranged/spells) and saving throws. If you cast an attack roll spell or cantrip with both buffs, you get 1d4 from bless and another 1d4 from mystras blessing. If you loose concentration only bless gets removed while mythras blessing stays on you for 10 rounds. The wording is just misleading but it is a very potent buff for attack roll spells that is active for 10 rounds no matter what. Besides that it does nothing.

The buff works with the characters own Bless spells as long as it is not upcast to levels above 1 (version 4.1.1)
