Since I play as the Necropolis faction, I prefer higher-tier liches and archliches. Archliches are almost essential in every final battle; they fight well, are durable, attack in a group, and can inflict plague at an opportune moment for the enemy. They are also great for defending the Necropolis. Higher-tier liches are my absolute favorite; I rarely engage neutral creatures without them. They resurrect units effectively, and with the Blood Dragon passive skill, they can do incredible things... In short, keep an eye on my replays and don't miss them! And visually, they are simply the embodiment of death; perhaps only the Undead look better. I simply adore them.
