RPG on the Portal.

The scream echoed again...
-Let's hurry! What darkness! I cast Magic Fire (minimum power - enough for illumination only).
Suddenly, ahead, we see a figure, as if leaning over a stone altar. A terrible laugh is heard, sending chills down our spines!!!

The scream repeats, now it sounds muffled...
-Howie, Wiz - forward!! I take out my bow, and without even understanding who is in front of me, I shoot at the figure... Damn, it's really dark here, my Fire's power isn't enough :( And why did I save mana????
It seems I hit! The creature howled in pain and darted towards us. It looks like my shot only made it angrier...
-Wiz, Howie, help!!!! (I'm not good in melee combat)
