OOC: You're absolutely right about Ari being able to draw the javelin while moving. So he is able to move forward to 10' behind Skarghash, thereby only putting him two range increments away for a -2. The +4 AC cover is still in affect though.
**********
Ari hustles his way through the trees, pulling one of the magical javelins from his quiver. Skarghash sees the monster hunter advancing on him and knows better than to raise his head. As the pirate passes into the clear, Ari heaves the javelin forward and it clips the pirate in the leg! [Attack javelin +1: AC 16 (cover) / 18+1+1=20 *hit* / 3 dam]
The pirate yelps and he grabs at his leg when suddenly an arrow whizzes by and pegs him in the arm! [3 dam] The pirate falls right next to his friend, but the more experienced of your group do not believe the two attacks have killed this guy, but rather he's probably just hurt badly and bleeding.
The five of you hurry out of the trees and advance into the camp. Khalia makes her way over to the pirate guards to check on their respective wounds, Ari, Taviss and Skarghash hurry over to the large tent to check it out, and Jango keeps an eye out through the camp in case there is anyone else coming through the trees.
When the three warriors lift the flap of the large tent, they see that is predominantly is filled with equipment. Based on the markings on the crates, chests and barrels, a lot of it probably came from the three ships that ran aground. However, the most important feature of the tent is the two large boulders that are half-buried in the ground. They are large and flat, and between them appears to be some sort of fissure or opening. The opening is large enough that you can see the top of a ladder sticking out of it, and a human sized person could easily fit within it and head underground. Finally, also coming out of the hole is a rope with a handle on the end, looped up and around a wooden stand. A quick knowledge check tells you that pulling the rope will most likely trigger something down inside the fissure. An alarm perhaps?
