/*
    Spell allows to add temporary poison properties
    to a melee weapon or stack of arrows

    The exact details of the poison are loaded from
    a 2da defined in x2_inc_itemprop X2_IP_POSIONWEAPON_2DA
    taken from the row that matches the last three letters
    of GetTag(GetSpellCastItem())

    Example: if an item is given the poison weapon property
             and its tag ending on 004, the 4th row of the
             2da will be used (1d2IntDmg DC14 18 seconds)

             Rows 0 to 99 are bioware reserved

    Non Assassins have a chance of poisoning themselves
    when handling an item with this spell

    Restrictions
    ... only weapons and ammo can be poisoned
    ... restricted to piercing / slashing  damage
