我觉得和用卷轴放是一样的吧?
so, who pays the XP cost for the spell effect made
permanent: the scroll creator or the individual who casts
the spell from the scroll? Who must meet the minimum
level requirement for making a particular spell permanent?
For example, see invisibility has a minimum level of 10th.
Does the scroll creator or the individual who casts the spell
from the scroll have to meet this minimum? Does the
minimum level refer to arcane spellcaster’s caster level or
character level?
In general, when you create a scroll with a spell that has an
XP cost, you have to pay the XP cost for casting the spell along
with the costs for creating the scroll (see Creating Scrolls in
Chapter 7 of the Dungeon Master’s Guide). Since the creator
has paid all the costs, the scroll user doesn’t have to pay them.
In the case of the permanency spell, however, it’s best to
make the scroll user pay the cost of actually making a particular
spell’s effect permanent. The scroll creator still pays the XP
cost to make the scroll.
You must use the spell’s caster level to determine if the
spell meets the minimum level to make a spell permanent. In
the case of a character casting a spell herself, the spell’s caster
level is the caster’s class level in the class that made the spell
available in the first place. For example, when a 12th-level
wizard/3rd level fighter casts any wizard spell, the spell’s
caster level is 12th.
In the case of a spell cast from a scroll, the spell’s caster
level is the scroll’s caster level. The scroll’s creator sets the
caster level for the scroll when making the scroll, as noted in
the Magic Item Descriptions section of Chapter 7 of the
Dungeon Master’s Guide.
