    The caster attempts to charm a group of individuals

    The spell starts checking the area and those that
    fail a will save are charmed.  The affected persons

/*
Patch 1.71

- was doing charm effect even for players (replaced for daze in this case)
- HD pool check corrected (if found target with HD matching HD pool)
- HD pool decreased also in case of spell being resisted
- added scaling by difficulty into duration
- added delay into SR and saving throw's VFX
- extended duration corrected to calculate twice of normal duration as usual
