After running the start of an adventure path I came across the Weaverworm as it is a new creature in the AP's bestiary. There appear to be some errors in the Weaverworm stat block (lists Initiative +18 when it looks like it should be +8), but there is one section where I am not sure if it is an error or just taking something very suboptimal to make it slightly less powerful.
Under the feats section the Weaverworm has weapon finesse. The problem with this is its Strength is 24 and its Dexterity is 18 which means the feat is completely useless to it. I know monsters are not optimized on purpose, but is this another error or intentional? Am I just missing something beneficial about having weapon finesse when your strength is higher than your dexterity?
Seems like combat reflexes would be an amazing feat for this creature with its 15ft reach and high dexterity though maybe it makes the creature too deadly for its CR. Any thoughts?
