Gremlin Nob
Gremlin Nob is an Act 1 elite enemy with 82-86 HP. It opens with Skull Bash, which deals 6 damage and applies 2 Vulnerable. It then alternates between Bellow (gains 2-3 Strength) and Rush (16-18 damage). Most critically, every Skill card the player plays causes Gremlin Nob to gain 3 Strength, punishing Skill-heavy decks severely.
Gremlin Nob is one of the most mechanically disruptive elites in the game. Its Skill punishment means that playing defensive cards like Defend significantly accelerates its Strength scaling, creating a brutal dilemma between protecting yourself and not empowering it. The optimal strategy is to minimize Skill plays and kill it as fast as possible with Attack-heavy turns. Power cards do not trigger its passive, so Powers played early in the fight are safer than Skills.
