I have made a fun spell for Pathfinder, with Lesser and Greater versions. Here is the spell:

Spell name: Inflict Random Summon Nature’s Ally Cure

Casting time: 1 standard action

Components: V, S

Range: 10 feet*D100

Spell Resistance: Roll D10. 1-5 — yes, 6-10 — no.

Duration: Instantaneous

Saving Throw: Yes, random to halve, natural 20 negates.

Base saving DC: 10+1D10

System:

I. Roll for spell’s range (10 feet*D100) and choose a target within it. You must see your target.

II. Roll D6 to determine the saving throw. Even if the spell happens to actually heal the target, it still rolls to save.

1-2: Fortitude

3-4: Will

5-6: Reflex

III. Roll D10 to determine spell’s damage type.

1. Positive energy 2. Negative energy 3. Cold 4. Fire 5. Electricity 6. Acid 7. Sonic 8. Bludgeoning 9. Piercing 10. Slashing

IV. If the target has spell resistance, roll D10. On 6-10 it doesn’t work, on 1-5 it does, even if the spell should heal the target.

V. Then roll for damage (or healing) inflicted, depending on spell version:

• Lesser — D20

• Normal — D100

• Greater — D1000 (Roll 3 D10 of different colour, just as you roll 2 D10 for D100)

If the number rolled is natural 1 or a natural round number, you become a chicken for 1D4 rounds.

VI. The target attempts to save. Natural 1 on the save roll doubles the effect of this spell, including the rounds you spend as a chicken. Natural 20 negates the spell.

Description: In desperation, you call for the help of the Chaos that shaped the universe at the beginning. A ray of something starts at your fingertip and aims at your target, and never misses, indicating reliability of that spell. The ray penetrates but doesn’t damage everything on its way to your designated target, and possibly somehow turns you into a chicken.

I think, it is clear that this spell is supposed to be a fun one, but it shouldn't actually become a game breaker. Of course, it should inflict more average damage than other spells of the same level due to how random and risky it is, but not too much.

So, which level should the normal, Lesser and Greater versions of this spell be?

VI. The target attempts to save. Natural 1 on the save roll doubles the effect of this spell, including the rounds you spend as a chicken if you do. Natural 20 negates the spell for both parties.

You cannot apply Maximize Metamagic to this spell by any power, it is already reliable enough.
