I'm really sorry I did not get back to you to answer your question. I hope you don't think I was ignoring you, I just got busy this week with RL.
Now for that clarification............
With all the debris littering the room to not have at least looked every few seconds to the path before you would have meant I would have had to make a number of dex type rolls to see if you fell. Plus the creature attacking happened so fast even if you had shouted a warning no one would have been able to attack before it reached Ulthok.
The only reason Aliya was able to hit it was she was rt there sword ready and the creature did not care about her. It wanted Ulthok for some reason until all the magic started flying and it knew it had to attack the spells coming at it at the main source, Sirene and Cor.
To everyone. If I don't get back to you right away on a question or a topic please do not think I'm ignoring you. Real life right now is busier for me then normal as Mom slowly gets better. I promise I will answer as fast as I can. Bear with me for right now. Thanks
