↖ Mapping Capabilities

This build is known for its excellent mapping capabilities, thanks to the combination of the Carcass Jack and the ascendancy, which provide 50% and 60% increased area of effect, respectively. The build also benefits from the Herald of Ice and Herald of Ash explosions and the Lightning Warp setup, which is supported by Less Duration and Swift Affliction to increase mapping speed.

↖ Single-Target Damage

The build is also incredibly strong in single-target damage, thanks to the new Lightning Tendrils skill, which doubles the damage of the old version by exploiting the stronger pulse, creating mechanism and phantasmal quality. To maximize the single-target damage, the best route is to use the Heat Shiver and Maryland's Fallacy unique items. The PoB link provided in this guide shows a DPS of 70 million.

↖ Budget-Friendly Setup

One of the most attractive features of the this build is its budget-friendly setup. While the guide author invested around 45 divine orbs into the build, only 30 divines were invested into the exploded flask for map clearing and Progenitus for defence. Most of the other gears are cheap, making it possible to have around 37 million DPS with good mapping and okay-ish defence for under 10 divines.

↖ Key Points to Consider

When building the Lightning Tendrils Elementalist character, there are a few key points to consider.

• First, the Carcass Jack is a must-have item, as it provides 50% increased area of effect, live resistance, and evasion ES, which fit the build perfectly. 
• Second, the Lightning Warp setup is important for increasing mapping speed, and the Immortal Flesh belt is necessary for low-life builds with Petrified Blood. 
• Third, make use of the exposure from the ascendancy to reflect and lower resistance. 
• Finally, remember to take advantage of the crossbow tree, which provides critical multipliers and a chance to scorch enemies, lowering their elemental resistance by up to 30%.
