Ilrusi Atoll - Demolition Duty  

When entering zone, one member of the party must be chosen to guide the Demolition Automaton to each of the five Shipwrecks (comparitive to how one must click on an Escort NPC to start/stop it). This member must click on the Start NPC to begin this task.

There are imps around the zone that aggro to true sight, so having a SMN on board is a great idea in case of unwanted aggro and keeping the automaton healed.

When you find a shipwreck, keep in mind only the automaton is able to affect the shipwreck, so just let it do the work. The shipwreck doesn't envoke any damage, but crabs do pop out of each shipwreck, I'd estimate 3-4 times at each location. When a crab spawns, each member of the party is able to fight the crab, making for rather quick crab fights.

The automaton will automatically engage on the crab and there's no way you can voke the crab off the automaton. Therefore, it's very important you have a mage continuously targeting the automaton and making sure it's always healed near 100% HP. I did try hasting and protecting the automaton, but I was not able to cast these buffs on the little bugger. Perhaps they changed this since I've done this assault.

Crabs seem relatively easy to destroy, so this assault could definitely be trioed, as long as you don't aggro imps at all costs. That could cause a potential loss since those imps could be difficult to fight @3 under certain conditions and time constraints.
