A combination of Thunderbolt and Ice Beam on the same set that is resisted only by Magnezone, Volt Absorb Lanturn, Shedinja, Frost and Heat Rotom, Seaking with Lightningrod and Mamoswine with Thick Fat. May also be used for any combination of Electric- and Ice-type moves, such as Thunderbolt and HP Ice.
So it's basically a combination of T-Bolt and Ice Beam.(Or any Electric and Ice moves)
Hope This Helped :D
