The lava creature holds up one hand to the side and makes unintelligible sounds. There seems to be a heat ripple, a wave of coalescing superheated air that then turns into a swirling fire and then a round fiery hoop. Another of the creatures steps through the gated portal, and it closes behind him. You now face two of the lava creatures.
Kallad swings his sword around. He hits the first lava creature in the chest. (10 hp dmg). When he draws back his sword, it is glowing red from the heat. Kallad himself is injured by being so close to the heat-intensive creature. (2 hp dmg).
Sir Floradine swings his two handed sword, hitting the creature at the base of the neck. (12 hp dmg). He too is damaged by the heat. (2 hp dmg). The creature, angered and deeply wounded, strikes out with its fist, hitting Floradine. Although the impact of the fist is only minor, Floradine's clothes burst into flames. (1+6=7 hp dmg) Floradine falls back and must spend the next turn putting out the flames or be burnt. His sword also glows red from the heat.
Joseph fires an arrow, just missing the creature.
Shae casts a spell, healing Joseph. (+6 hp).
Illborn pulls the lever. You hear the whistle in the niche and a click from the top of the pyramid where the first creature stands.
The second lava creature stands still but begins making a strange gurgling sound.
Joseph lets loose another arrow, this time hitting the lava monster. (5 hp dmg). The creature grasps at the arrow and falls back over the pyramid and into the molten lava moat. He seems to dissolve directly into the moat.
