You never mentioned how far you were, so its a bit late to add in more details. Such is why specifics such as attacking with the left or right arm are important too. 

Of course I figured that safe range was a moot point, since all he needs to do to escape an explosion is shadow away, which you mentioned he'd do the moment he loosed the arrows. The reason provided for him distancing himself is negligible.

Basically, there's no logical justification in just now mentioning that Crual is out of the monster's extended range. Otherwise I could potentially claim something like the tunnel they are in being only as long as the monster's reach, since it was indeed  made by me to accomodate the creature with no exact specifications given.
