Odd D&D-to-GURPS translation

[simulatoralive]

I built a version of that spell for my wiki ages ago: http://islandsofwar.wikispaces.com/R...List.Sanctuary.

I did it with the Mind Control approach, so perhaps not what you're looking for, though.

Any ideas? I don't mind if it involves advantages or spells. Thanks!

If you don't mind about the exact GURPS point costs/mechanic, you could simply port the D&D mechanic "as is", like that:

"Anyone who wants to Attack you in melee combat has to make a Will ROLL or simply not be able to attack you."

Revulsion needs a much larger range to prevent missile attacks.

The spell is only supposed to affect melee attacks.

This is from the 3.5 SRD:

If the save fails, the opponent can’t follow through with the attack, that part of its action is lost, and it can’t directly attack the warded creature for the duration of the spell. Those not attempting to attack the subject remain unaffected. This spell does not prevent the warded creature from being attacked or affected by area or effect spells. The subject cannot attack without breaking the spell but may use nonattack spells or otherwise act.

Just for fun, here's my attempt:

Sanctuary

34 points for level 1, plus 5 points for each additional level

Touch the subject and roll vs. Will -- if the subject chooses to resist, make this a Quick Contest of Wills. If you succeed (or win), the subject gains a Sanctuary Aura for seconds equal to your margin of success (or margin of victory; minimum 1 second). Anyone within the subject's Sanctuary Aura must succeed on a Will roll each turn or be unable to attack the subject for seconds equal to their margin of failure. If the subject attacks anyone, the effect ends. At level 1, the aura has a radius of 2 yards -- each additional level doubles the aura's radius.

Statistics: Affliction (Will; Advantage, Sanctuary Aura, +140% +50%/level; Based on Will, +20%; Malediction 1, +100%; Melee Attack, Reach C, -30%; Nuisance Effect, Terminated if subject attacks anyone, -5%; Reduced Duration, 1/60, -35%) [29+5/level]. The Sanctuary Aura is Affliction (Will; Area Effect, +50%/level; Aura, +80%; Based on Will, +20%; Disadvantage, Pacifism (Total Nonviolence; Subject Only) [-5], +5%; Melee Attack, Reach C, -30%; Reduced Duration, 1/60, -35%) [14+5/level].

Add some spell-like modifiers if you want. Adding Costs Fatigue, 2 FP, -10%; Magic, -10%; Requires Gestures, -10%; Requires Magic Words, -10% would reduce the point cost by 4. Also consider adding Based on IQ, +20% to make your success roll against IQ instead of Will (and the Quick Contest your IQ vs. the subject's Will).

Level 1 will protect the subject from close foes, levels 4-5 will protect them from everyone in a typical low-tech melee, level 10 will protect them from everyone in about bow range, and level 26 will protect them from everyone on the planet.

When is the Will saving throw made in D&D? What happens if it fails? Is the rolling character free to choose to attack some other target, or has he wasted his attack action for that round?

If it's a spell in the original source, why not convert it as spell to GURPS?

[Verjigorm]

Of an Affliction that has Malediction, maybe aura, and Total Pacifism(only towards cleric)?

Further musings, assuming the 3.5 version of the spell, like found in the HyperText SRD. The power makes the attacker lose his action if he tries to attack the spell subject and borks a Will save.

GURPS Magic framework: It's pretty close to what the Command spell does. Turns it into an active defence with all that entails, but it's a pretty GURPS'y approach. Avoid also has some of the properties sought.

As a Power:

It reacts to attack, so the Reflexive (+40%) modifier is probably needed.

It is very clearly Mind Control [50]. But it's a version of Mind Control with only one use, so it's a very limited form in that regard. It commands the specific action of aborting the action underway. Probably in the -50% to -75% range.

Mind Control needs concentration, though which means that the power will need the Independent enhancement (+70%) or it will also cost the caster his ability to act that turn.

The adherence only lasts a turn, though, and that's the Maximum Duration limitation for -75%.

So far this comes to +40+70-75-75 = -40% for an advantage cost of 30.

Now as a spell this now needs to be rolled into an Affliction [10]

Adding this advantage is +300%

It's touch only so the affliction gains the Melee Attack, Reach C, No Parry for -35%.

The part about ending if attacking is an Accessibility limitation (Only while not attacking) probably worth -20%

That the power only protects for a duration is built into Affliction.

Final cost modifier should then be +300-35-20% = +245%. 3.45 x 10 is 34.5, rounding to 35 points.

------

If one uses Multiplicative modifiers the costs become:

Base Power: 40%+70% = +130% to 50 points = 115, reduced to 20% = 23 points.

Resulting Afflicttion: +230% to 10 points = 33 points, reduced to 45% = 14.85, rounding to 15 points.
