The Frozen Orb build primarily uses just one skill, that of its namesake. The idea here is to hurl Frozen Orbs to the ground, shredding the area around them with Ice Bolts. Frozen Orb synergises with Ice Bolt, which can add 2% to Frozen Orb’s cold damage per skill level. Of course, since enemies can have immunity to cold, the build also includes a fail-safe so that your hireling can take out enemies for you. On top of that, the Energy Shield skill gives you more damage absorption and Warmth increases your mana recovery.
Before we dive into the equipment loadout, there are a couple of things that we should explain beforehand. First of all, a lot of the items have socketed items. Imbuing equipment with items such as gems or runes gives that item a boon that can make your build incredibly powerful. Adding an item to a socket is easy: click on the gem or rune you wish to move, then place it on top of the item you wish to socket. You can also remove gems and runes from weapons using the Diablo 2 Resurrected Horadric Cube recipe, though this destroys everything that’s socketed to that item.D2 Resurrected Items
You may have noticed that some of the hireling’s equipment has the Ethereal item flag. If an item is Ethereal, it grants a bonus to either damage or defence, depending on whether it’s on a weapon or armour. It also reduces any strength or dexterity requirements by ten points, and they repair themselves. There are downsides however, as if the Ethereal item breaks, it will stay broken. They also have half the durability of the regular version of the item, and about 75% of the sale value.
