I probably was too vague with location. Yes, Ananze moved so the tree no longer obstructed his aim. Ananze while not fast in the way a speedster character would be is agile, flexible, and very practiced at moving through trees so covers metaphorical ground very swiftly. As to the throwing, these shots were not said to be silent if I remember correctly, so it's more likely that Mr. Clock (just saying this so I don't have to type his whole name every time we talk OOCly) would be able to hear the rustling somewhat this time.

As to obstructions in the forest, Ananze may not have great normal vision, but he can see anything his web is attached to like a bright light. Granted the mana in those webs is very little so it would be little more "bright," to someone else as a flash light with a dying battery in an unlit room. So yeah, he did re-position. Also, Mr. Clock being on the ground would make him an easier target not a harder one as being in the trees means that Ananze has to potentially throw through even more foliage to hit his target(s), whereas on the ground such is less likely.

As to where I said Ananze moved. First paragraph near the end [quote]Flinching at the contact, the daedri's many eyes narrowed briefly before the arachnoid sprung into a blur of movement.[/quote]
Mind you I can entirely see how that could be misconstrued as the beginning of the next sentence where he throws the projectiles.
