Caltrops, is this really the intention?

[likuidice]

Caltrops: A caltrop is a four-pronged iron spike crafted so that one prong faces up no matter how the caltrop comes to rest. You scatter caltrops on the ground in the hope that your enemies step on them or are at least forced to slow down to avoid them. One 2- pound bag of caltrops covers an area 5 feet square.
Each time a creature moves into an area covered by caltrops (or spends a round fighting while standing in such an area), it might step on one. The caltrops make an attack roll (base attack bonus +0) against the creature. For this attack, the creature’s shield, armor, and deflection bonuses do not count. If the creature is wearing shoes or other footwear, it gets a +2 armor bonus to AC. If the caltrops succeed on the attack, the creature has stepped on one. The caltrop deals 1 point of damage, and the creature’s speed is reduced by one-half because its foot is wounded. This movement penalty lasts for 24 hours, or until the creature is successfully treated with a DC 15 Heal check, or until it receives at least 1 point of magical curing. A charging or running creature must immediately stop if it steps on a caltrop. Any creature moving at half speed or slower can pick its way through a bed of caltrops with no trouble.
Caltrops may not be effective against unusual opponents

Regarding the three statements in bold text: Do they occur regardless of whether the caltrop deals damage or not? For example, a balor charges the party, the party gets lucky, and the balor steps on a caltrop (successful attack roll) . The balors damage reduction protects it from any damage, but it seems it still must stop its charge in that square, and, next round, it's speed is reduced by 50%.

Is this all correct?

The caltrop requires an attack roll and as it deals physical damage it qualifies for DR. Which it will never penetrate.

Nup, if you go hunting Balor's you may need a bigger weapon.

From the SRD:

Whenever damage reduction completely negates the damage from an attack, it also negates most special effects that accompany the attack, such as injury type poison, a monk’s stunning, and injury type disease.

Since the Caltrop make an attack roll, can this be "exploited" through feats or spells? Perhaps a Magic Weapon'd caltrop would do more damage? Or a Caltop that can Cleave

I think that is called a "land mine"

Silver & cold iron brilliant energy caltrops?

Although it seems silly to keep this going. I can't resist.


Maybe you could make a +1 Flaming Burst Caltrop Now that would be a land mine. Too bad you can't True Strike it....

Check out the listed <i>why</i> of the slowing -

because its foot is wounded

If the foot isn't wounded (due to DR or some other effect, such as 1 point of healing (which is a special effect of many types of DR....)). I'd say no, it doesn't slow down if it can't take any damage from the caltrop.

A balor? i am going to say that the caltrops melt unless they can withstand 6d6 of fire damage.

A balor stands about 12 feet tall. Its skin is usually dark red. It weighs about 4,500 pounds.
Combat

Balors love to join battle armed with their swords and whips. If they face stiff resistance, they may teleport away to loose a few spell-like effects at the foe.

A balor’s +1 flaming whip is a long, flexible weapon with many tails tipped with hooks, spikes, and balls. The weapon deals bludgeoning and slashing damage, in addition to fire damage.

A balor’s natural weapons, as well as any weapons it wields, are treated as chaotic-aligned and evil-aligned for the purpose of overcoming damage reduction.

Death Throes (Ex): When killed, a balor explodes in a blinding flash of light that deals 100 points of damage to anything within 100 feet (Reflex DC 30 half ). This explosion automatically destroys any weapons the balor is holding. The save DC is Constitution-based.

Entangle (Ex): A balor’s +1 flaming whip entangles foes much like an attack with a net. The whip has 20 hit points. The whip needs no folding. If it hits, the target and the balor immediately make opposed Strength checks; if the balor wins, it drags the target against its flaming body (see below). The target remains anchored against the balor’s body until it escapes the whip.

Spell-Like Abilities: Caster level 20th. The save DCs are Charisma-based.

At will - blasphemy (DC 25), dominate monster (DC 27), greater dispel magic, greater teleport (self plus 50 pounds of objects only), insanity (DC 25), power word stun, telekinesis (DC 23), unholy aura (DC 26);

1/day - fire storm (DC 26), implosion (DC 27).

Vorpal Sword (Su): Every balor carries a +1 vorpal longsword that looks like a flame or a bolt of lightning.

Summon Demon (Sp): Once per day a balor can automatically summon 4d10 dretches, 1d4 hezrous, or one nalfeshnee, glabrezu, marilith, or balor. This ability is the equivalent of a 9th-level spell.

Flaming Body (Su): The body of a balor is wreathed in flame. Anyone grappling a balor takes 6d6 points of fire damage each round.

True Seeing (Su): Balors have a continuous true seeing ability, as the spell (caster level 20th).

Skills: Balors have a +8 racial bonus on Listen and Spot checks.

Welll, you could add an extra enchantment to the animated caltrops (magic item that is in CAd IIRC). Those are actually animated constructs, so it is theoritically possible they could be made to trigger a True Strike on themselves.
