Don't look too much into some of the fancy items, they don't matter.
The core of the tech is to utilize entangle's ability to instantly hit anything that is placed on top of it. This combined with the interaction between Biting Frost and Ice Crystals makes entangle an incredible tool to instantly detonate frost walls that are placed on it.
Between Multishot and Fortress, each shot of Glacial Bolt creates upwards of 54 instantly exploding frost walls as long as they are placed on top of an entangle supported by Biting Frost.
The tech has applications over almost every Frost Wall-esque skills.
If you have any question, I'll be happy to answer them !
