The pinnacle node Icefall in Diablo 4 is very important in the game, especially for some special professional players. The peak node Icefall also has many characteristics. First of all, Icefall can greatly improve the ice skills. Survivability, especially with ice ring, frost burning, frostbite, freeze spread, etc.
The peak node fell into ice. This is a more questionable choice. Death Ice indeed greatly improves the survivability of Ice Mage, especially when combined with Ice Ring, Burning Frost, Frostbite, Freeze Spread, etc., it performs very well.
However, the quality of the Death Ice Disk itself is extremely poor. It needs frostbite shoes, frostbite enchantment, or permanent freezing to perform well. This is difficult for a mage with only two enchantment slots to have both.
If you don't follow the Frostbite style and forcefully choose the Death of Ice node, it's hard for me to say whether this will strengthen or weaken it. After all, the bonus of the glyph is too obvious.
