Dark Elves — guide

In this section we will analyze the faction, recommend the best heroes and show builds for completing floor 21 of this faction

First option

A Faction Wars completion option for Dark Elves.
If you put, for example, Madame in the team with Visix instead of Rae, then a revive might not be needed. But it will be slow.
If with Foli and Rae, then mine died, but it's faster.
Visix is actually very useful, I don't recommend ignoring her. All her skills are useful. Without Martyr (or, as an option, Tymila) I wouldn't have managed at all, Kaiden will simply die sooner or later (I checked).
Sylar played a huge role, but as an option it's another Champion with an AoE hit (some completed it with Luria) in a Stun set.
Good luck!
