Coldberus

There’s a frozen room in hell, especially designed by the Devil, where heat-loving sinners go. There they suffer unbearable cold for eternity. Coldberus guards this room to make sure that those souls never get out.

Overview
Coldberus is a control monster with an unfortunate amount of status effects. The status effects he inflicts include Freeze, Nightmares and Stamina Removal

Pros:

 * Good trait
 * Okay relic slots
 * 50% stamina removal on all enemies
 * Low cooldowns and stamina costs
 * Good damage output for a control monster

Cons:

 * Bad stats
 * Limited status effects
 * Only one AoE move

Fully control

 * Frozen Expiation (40 Water dmg + Freeze, 26s, 1cd)
 * Horror Walkers (50 Dark dmg + AoE Nightnares, 26s, 1cd)
 * Stamina Payment (AoE 40 Water dmg + 50% Stamina Drain, 33s, 3cd)
 * Nightmare Beings (40 Dark dmg + Nightmares, 24s, 0cd)

Here, Coldberus does more controlling than damage. Frozen Expiation freezes an enemy. Horror Walkers gives nightmares to all enemies, and Nightmare Beings is the single-targetted version. Stamina Payment is a highly-damaging AoE move with stamina drain, but with a high cooldown.

Recommended Runes: 3 Speed

Attacking control

 * Triple Bite (60 Dark dmg, 27s, 2cd)
 * Obscure Chew / Nightmare Beings (50 Dark dmg, 20s, 1cd)
 * Frozen Expiation / Horror Walkers
 * Stamina Payment

Here, Coldberus also attacks. Triple Bite is a high damage dark move, and Obscure Chew deals less damage but has a lower cooldown. If you run this move and Horror Walkers in the same skill group, you have free 50 dark damage every turn until Coldberus runs out of stamina.

Recommended Runes: 2 Power, 1 Team Speed

Recommended Relics: Energizing Amulet / Healing Amulet (They must be at a high level), Pestilence Trap

Counters

 * He depends on freeze for his denial, so monsters that are immune to freeze will destroy Coldberus' main gimmick. Avaast can stun Coldberus and remove his stamina and HipHopotamus can remove the freeze that Coldberus applies. Coldberus' freeze is also single target, so HipHopotamus doesn't need to waste Back In Track to cleanse.
 * Kaori is faster than Coldberus, so she can run Be Water as her first move to make sure that Coldberus can't deny her. She also has two hard-hitting moves that can destroy Coldberus due to his low health.
