1°) Usually, unique and set (?) items (and perhaps rare items) cast their spell at a higher level than more common items do.

For instance, as per v1.03.25, the Orb of Etheria cast a 5th level Soul Flame!! That's higher than any Pyromancer hero could. A 5th level Soul Flame has the following effects: +30 XP (+10 XP + 5 XP/mastery level) to some units in the Command radius, capped at 50 XP (10 XP / mastery level). That means that two triggers are enough to build a level 5 army with a low intelligence hero.

2°) What if the hero already knows the spell that the item will trigger? Do the mastery levels stack (hero + item)?
