Frost Mage's Piercing Cold, how many spells affected by it exactly

[spyvsspy]

Hi. From the wiki I read that the following spells are affected by Piercing Cold:
Burst of Glacial Wrath, Cone of Cold, Creeping Cold, Greater Creeping Cold, Hypothermia, Icelance, Ice Storm, Lesser Orb of Cold, Orb of Cold, Polar Ray, Ray of Frost, Frost Breath

But I read the discription of Rainbow Blast that said the cold part is also affected by it. So I wonder if there are other spells which are affected by Piercing Cold that wiki did not mention?

Considering Wiz/Sor spells only now:
Kaupaer's Quick Blast
Snilloc's Snowball
Rainbow Beam
Dark Bolt
Ice Darts
Snilloc's Snowball Swarm
Tiramael's Energy Spheres
Greater Rainbow Blast
