/*
    The weapon used to trigger this should contain two
    local ints:
    pois_wpn_idx  - The number of poison to use. Matched
                    against poison.2da
    pois_wpn_uses - The number of uses remaining.

    The script first makes sure that both ints contain
    valid values. If uses is 0 or less, they are both
    removed along with the itemproperty.
    The removal also happens when uses run out.

    The actual effect is an EffectPoison being applied
    to the target. The poison used is determined by
    pois_wpn_idx.
