Well, Gjall is nothing short of a big floating pain with little ticks and every present seekers. Wiped out an outpost with a pile of defenders. However, what this biome has taught is to develop recovery teams and plans. More times that naught, after a few minutes 0r 1/2 game day, I roll into trouble. It usually takes 3 or 4 attempts to recover, and creatively at that. No other biome was as difficult and I spend 1/2 the game time recovering or preparing to recover. Portals set up all over the place. Troll armor and plenty of stamina. Rafts prepared and ready. Wisps lights a plenty - or sometimes run blindly. Can only do this so much.
