    Transmutation
    Level: Sor/Wiz 5
    Components: V, S, F, M
    Casting Time: 1 standard action
    Range: Medium (20M)
    Area: 6.67M-radius (20-ft) spread, centered on 1 target creature
    Duration: Instantaneous

    Source: Various (Andvaranaut)

    Upon casting this spell, a small vial of your own blood flies throught the
    air towards a designated target, which it strikes unerringly. In flight,
    the blood crystalizes and begins to become explosively unstable due to the
    magical energies channelled into it. Upon impact, the vial and blood
    crystals detonate, dealing 1d6 points of damage per 2 levels (to a maximum
    of 10d6) to all within the area of effect. This is non-elemental damage, and
    thus not subject to damage reduction from such spells as Protection from
    Elements.

    Additionally, all those unfortunate enough to be caught in the blast are
    knocked prone and coated with a fine, dust-like coating of the blood - until
    recently - contained within the vial. Unless completely washed off, by
    resting, or after 24 hours, the blood begins to reek, and will give a -4
    penalty to hide checks until the blood is removed.

    A successful fortitude save halves the damage dealt by this spell, and
    prevents the character from falling prone.

    The focus and material component for this spell is a small vial of your own
    blood (roughly 2hp worth).

    Perfectly fine.

    Originally it was +4 to people tracking them, but I think -4 to hide checks
    are just as fine.

    That part isn't savable against. The proneness is, and the damage is.

    Need blood effects (eeewww!)
