The subtle caltrop is a spell of incredibly minor potency, only notable due to the sheet cleverness of its construction and specificity of its spitefulness. No grand words or accumulation of power is required to invoke the spell, with the only outwards sign of its invocating being the slight tapping of a foot.
For those who know this spell tapping their foot twice and glancing at a target will cause a vicious caltrop to appear underfoot on their very next step. Each of the 4 tips is pointed slightly differently.
| 1d4 | Point |
|---|---|
| 1 | Wickedly barbed like a manta ray spin |
| 2 | Blunted, designed in such a way as to slip out from underfoot and trip the victim |
| 3 | Weakened at the base to snap off in the wound |
| 4 | Delicately inscribed with rude and phallic imagery |
Knowledge of this spell comes with a price however, for once known the caster becomes subject to its peril. If not cast at least once every seven days a caltrop will appear under the caster’s foot at an inconvenient time.
