When an enemy Target casts a
Spell, any
Caster who is has at least 1
Skill Point in
Magic automatically rolls an
Magic
Skill Roll to
Identify the
Spell.
The DC is 15 +
Spell level. If the
Caster has the
Spell as a known
Spell, then they roll with
ADV.
This opens the possibility to Counterspell.
This also works the same way for hostile Targets if they have the
Ability to
Counterspell.
If no one has Counterspell, the
Spell goes off as intended with the
Spell name revealed in the combat log.
