Some items from G Plus posts I haven't put here yet, or have updated.
Leeching Orb - When the effect of a spell or magic item is used on the holder of this orb, the effect happens as normal, but the caster or item then makes a saving throw. If failed, further charges of the item or spells from the caster's brain are absorbed by the Leeching Orb until a save is passed or 5 charges are absorbed. This process will continue even if the holder of the orb throws it from their person. When 5 charges are absorbed, the Leeching Orb discharges as a Chain Lightning directed away from the orb as if cast by a 5th level Magic User. The orb is then destroyed.
