Guild Wars 2

Good Day to all:
I have the idea of making a good app for GW2 most for storing Builds and stuff (android app). I plan on getting data from gw2 API. and of Course ill be using Images from GW2 Art.
My question is: Android app will be free with some “paid improvements”, DO I HAVE to ask permission to ANET to use their ART ICONS or their API? do i have to pay them a % of earnings (if i have any)? I dont wanna work and then get issues with ANET (legal).
Or just to avoid all that make the app free with ADS?
Everyone can answer but i would be nice if some from ANET could send me into the correct direction to get answers.

Thanks for your time Community.

I followed Stardriver.7459 ’s suggestion on my second run of this story and completed without any difficultly.

First talk to Demolitionist Tonn to get the group of NPCs moving, instead of following them east through the cave, go north (to the 3rd tower) and Tonn will tag along. The mobs along the way can be pulled one by one very easily as you work your way up. Just before reaching the tower, revive a dead Wyld Hunt Technician, who then goes to revive more of his friends. Clear the tower of its surrounding risen. I then moved south along the shore to clear out the second tower, then carefully around the first tower.

This method is a little easier I think and safer than running ahead to aggro the risen away from the tower as others have suggested. There’s less chance of any risn getting stuck because you’re clearing the last and second tower that Tonn won’t blow up yet.

Continue as normal after blowing up the first tower, moving back to the second tower, then following the Pack Marmox back through the cave. Unlike the others in the NPC group, the Marmox will stop just before the Wyld Hunt’s tent, which is normal. 3 more risen will pop out near the 3rd tower. They are at a safe distance away from it – but kill the one closest to it first anyway was my thinking.

You’ll know all is fine afterwards when the objective is to talk to Tonn again to make a story decision.

WORKED PERFECTLY THIS WAY FOR ME!!!!

I have the same problem today 18/09/12 i cleared all mobs no mob glitched and the cut scene does not work!! in the last turret the little asura destroy the turret at the moment it gets out of combat, maybe if you kill everything before blowing might work, anyways is a bug and must be repaired.
