My friends and I are playing D&D 5e. Our DM has allowed me to use the Arcane Tradition of Lore Mastery from Unearthed Arcana: Warlock & Wizard. I have a question regarding its Spell Secrets and Alchemical Casting features used in conjunction with spells cast from Wands or Staffs.
It has been confirmed by Jeremy Crawford himself that if an item's description says that you cast a spell from it, then you can apply metamagic to that spell.
My question is whether this applies to the abilities of the Lore Master wizard as well.
Can a Lore Mastery wizard use Spell Secrets or Alchemical Casting to modify spells cast through wands or staffs?
I'm specifically wondering about the wand of lightning bolts and wand of fireballs. I'm trying to see if I can use my abilities as a Lore Mastery wizard to change the damage types of the spells I am casting from these wands.
