This is as far as I've gotten on the spells and reversals, but I think this will hold me for a long period of play.
Continual Light
4th level Reversals: Continual Darkness
Detect ‘Evil’
4th level Reversals: Alignment Ward: The reverse of
this spell protects one target from registering under the “Detect Evil” spell
for one day per caster level.
ESP
4th level Reversals: Thought Ward: The reverse of
this spell protects one target from having their thoughts read for one day per
caster level.
Feather Fall: Duration: 8 hours or 1 turn: The
caster protects themselves against falling (and falling damage) for the next 8
hours. Any time during this period that the caster starts to fall, they float
at a non-threatening pace to the ground. At any point during the 8-hour
duration the spell the caster may re-direct this to another living creature or
unliving mass of up to 5000 coins (500 lbs); the caster loses the advantage of
the spell, but the new recipient gains it for 10 minutes.
4th level Reversals: Levitate
Find Traps
4th level Reversals: Rune Trap: The caster can place
a rune onto any space or on any object that has no effect other than convincing
people that there is a trap. A Save vs. Spells is needed to overcome the belief
that it is trapped. The rune is permanent, but takes 10 minutes to cast.
Glamour: This spell creates or changes appearances
within the area of the spell effect: up to a 20' x 20' x 20' cube. The caster
should create an illusion of something he or she has seen.
4th level Reversals: Suppress Glamours: This spell
suppresses any active illusions inside a 20’ radius of the caster. This effect
continues for concentration: free standing illusions are dispelled, but those
that are permanent parts of the dungeon, or are being actively maintained via
concentration by magic-user or elf casters, will reappear when the caster stops
concentrating.
Invisibility
4th level Reversals: Detect Invisible
Wizard Lock
4th level Reversal: Knock
Locate Object
4th level Reversal: Divination Ward: The reverse of
this spell allows the caster to create a magical protection against anyone
scrying on them (or their conversations if other people are talking to them)
lasting 24 hours. This blocks magic mirrors, crystal balls, clairsentience, and
similar spells.
Mirror Image
4th level Reversal: Phantasmal Forces: The reverse of
this spell, rather than creating duplicates of the caster, creates a number of
phantasmal warriors equal to the caster’s level that appear in the most
believable fashion the caster can contrive within 60, and attack the caster’s
enemies as per the Glamour spell. The each solider ‘dies’ if hit, gets 1 attack
per round, and does 1d8 damage per hit. These phantasmal forces will move and
act in a believable fashion for 1 turn, must remain within 60’ of the caster,
and do not require concentration to maintain.
