No save unless indicated.
Duration is permanent or instantaneous unless otherwise indicated. Remove curse will get rid of the thing where appropriate.
So it's like two creatures agree and you cast this spell and they have any kind of contest they agree to for any stakes they agree to but the magic makes it so they have to do it or the not-agreeing creature melts.
Grief to Steel
So you're not sad any more but/and your sadness becomes a cage. GM rates the target's grief on a scale of 1 to 10. 10 being like your civilization was just destroyed, 1 being you lost a decent sized investment or a pet you were just getting to like. Cage has d8 times that many hit points. The cage can be any design the caster likes and any size up to 20' x 20' x 20'--so it can be used offensively or defensively.
Affects all sad targets adjacent to main target.
Laughter to Pain
How funny was that? On a scale of 1-10? Well that's how much it hurts. d8 times that damage. If it is unclear how funny the thing is (the GM laughing is a good sign it's in the 8-10 range) then you can ballpark a number by having the target a will-based save. Spell can be cast instantaneously.
Affects all laughing targets adjacent to main target.
Caster touches target and an object. Target saves--a failed save means the target becomes obsessed with the object. The target must do things like make a will or spell save to get away from the object and otherwise avoid acting all Gollum about it in any other circumstances. The target is at -4 in combat if not touching the object on account of being distracted unless it is actively fighting to secure the object in which case it is at +4.
Drunk Reversal (this is an old one)
Switches the blood alcohol levels of two targets in range. Both switchees must be able to stand and the actual reversal happens when they touch.
Range: 20 feet
Two targets are chosen: a "donor" and a "receiver". The receiver becomes completely aware of the donors struggles in life on the most visceral level. The receiver knows the donor's most powerful desires and fears but will not consciously act to exacerbate the donor's situation. Unless the donor creature is suicidal, the receiver cannot harm the donor in any way. The receiver may, if s/he desires, make a will/spell save to stop the feeling once every 24 hours but the knowledge gained remains.
Tenzill's Metabolic Distortion
Target can no longer metabolize ordinary food but can eat a substance chosen by the caster as if it were food. The caster must freely present a meal's worth of this new "food" to the target in order for the spell to work (the caster cannot willing impose any obstacle between target and food).
Aura of Corpulence
Area of effect: 15' radius from caster
Duration: d6 rounds
Anyone entering the spell's radius becomes enormously overweight and must make a strength check to take any action requiring movement. Armor may burst. If the targets escape the spell's radius, they can start making will/spell saves each round to regain their previous shape.
Caster chooses a word. The target takes d10+(caster level ) damage each time s/he says it (unless the word is used as part of a magical incantation and is essential to that incantation, in which case the word is temporarily protected). The target will sense the word it cursed after the first instance.
Caster chooses a target secretly (writing it down if necessary). Whatever action that target next takes occurs. However, thereafter that action is cursed and doing it again (ever) will cause d6+(caster level ) damage to the target. The category of action then cursed will be generally be defined by the act (attack or speak, etc), the tool used (specific weapon or spell or words) and the target. So it could cover "attacking Phil with an axe" or "casting magic missile on Leroy" or "saying Fuck Off to Annabelle". However, the caster may choose one of the categories and extend it to cover that class generally if s/he can roll under his/her level on a d20. A curse on "Attacking Phil with an axe" could be extended to "Attacking any human with an axe" "Attacking Phil with anything". "Saying Fuck Off to Annabelle" could be extended to "Saying anything to Annabelle" etc. The target will sense the action is cursed after the first instance.
Caster prepares food. The caster may then see through the eyes of any who eat that food for 24 hours after they eat it.
A 'seed' target is chosen and an invisible aura surrounds the target for 5 minutes. No creature that attacks the seed target while the aura is present may ever attack any other creature that attacked the seed while the aura was present. Like, ever.
Ildiko's Hideous Minstrels
(Caster level) x 20 minstrels appear within 40' of the caster, gamely clutching their instruments. They are unaligned, obey no-one, and cannot be reasoned with. They will all play and none will play well. With luck, they may disperse.
The caster transforms one or more of his/her hit dice into a small plover or thrush. This bird then flies away and hides, the caster's hit dice are lowered by the appropriate amount. Should the caster be slain or reduced to zero hit points, s/he will not die. The bird will immediately seek the caster out, gives back the remaining hit dice and dissolves.
Caster touches a hog, heifer or other piece of livestock. All who gaze upon it thereafter must save or become despondent (-2 to all saves) for one week.
Fruit of Ruination
Caster designates a fruit. The first creature to eat of that fruit will immediately begin behaving as if his or her Charisma and Wisdom are 3 toward the first ally s/he sets eyes on thereafter. All of his or her negative traits will be exaggerated in any conflicts with the unfortunate ally.
Range: 20' radius around caster
Anyone except the caster within the radius will have all of their negative personality traits exaggerated and will behave as if their Charisma and Wisdom were 3 in terms of interpersonal behavior.
Caster secretly designates a target. As soon as the target touches something old, then new, then borrowed, then blue s/he takes d10 damage per caster level. Objects the target is in contact with when the spell is cast do not count, and no object counts for more than one category.
Warsong of The Avoider
Target rolls a d20. Target can be knocked unconscious but cannot be slain until s/he rolls that number again or an attacking enemy does.
Warsong of The Despised
Target treats damage as healing and healing as damage. Once out of combat, the target will slowly begin to die due to natural healing. (Yes, you can live forever if you keep stabbing yourself. Totally intended.)
