The Gunship Battle in ICC is one of the easiest and more exciting battles that you will find in end-game content by far. It is, in fact, so easy, that it doesn’t even merit a walk-through but I’m’a do it anyway because it is also one of my favorites.
OK, so you’re on the boat. Remember to always equip the jetpack. This is mighty important for you, as a shaman, because otherwise you will not only not contribute to the success (or only marginally) but you can also be the bringer of death and sorrow, namely of a wipe. This is, of course, given the fact that you are stepping into ICC for the first time and are not at a vast disadvantage, gearwise, compared to your group. After you have the jet-pack equipped it’s very important to ask what is expected of you for this fight. There are a number of viable scenarios as to how this battle can be won so make sure you know what your part in it all is. Most likely you’ll be on add duty and that is the easiest part of the easiest battle. You just have to grow roots in one place near the ledge of your ship and go all out on the dwarven riflemen on the other side. CL is a good idea for this part, because said riflemen will be shooting at your ship and try to take it down. More on this later.
You will see that there are two cannons you could use but usually they are assigned to specific people so unless told otherwise, stay clear of them because you’ll be most likely mocked for your gunnery affinity. If you are assigned to be in a cannon, however, the only thing you need to do is to spam 1 until the heat bar to the right of the ‘vehicle’ UI goes up to around 75%-90% and then pres 2. A normal way to start causing more damage (albeit not a lot) is to pre-heat the cannons by starting firing them once the gunship is on the move so that you can use the special attack as soon as possible on the enemy ship.
Now down to the nitty-gritty, (if only) the fight itself. Your job will be to kill the enemy’s riflemen. Normal rotation on these guys, FS, LvB with the addition of CL off CD. Don’t worry about mana, it’s EZ mode, trust me on this one.
From time to time you’ll hear Muradin asking for a mage to come to the stage (‘Get a Mage in here to freeze those cannons!’ I believe are his exact words), and your cannons will be enclosed in a block of ice and their respective gunners will be ejected. At this point the jetpack kicks in and you’ll have to board the enemy ship and kill that pesky mage as soon as possible. Once he’s down the cannons return to normal and the group can have at it again. Rinse and repeat until the enemy ship starts going down in flames. Loot. But make sure you’re not actually aboard the enemy ship when it starts descending or you’ll be going down with it. Like a captain. With a another faction’s ship. Erm… yeah…
A little tid-bit about the riflemen. Make sure you snipe all of them, otherwise the longer they stay up the stronger they become and the more they hurt your ship.
This was the offensive part, now for defense: to make your healer’s lives a lot easier when you see that there’s a circle under your feet get outside it’s radius and start blasting again. That’s where a rocket is going to land and even though it doesn’t hurt that much, multiple rockets can kill you if you’re not paying attention. Be wary also of Muradin’s cleave. It hurts like a MOFO even though you’re wearing mail so make sure that when you jump over to the enemy ship:
a) You’re not the first one otherwise he will come get you and turn you into a smear on the floor.
b) Make sure that you don’t target him at some point and start unloading damage in his arse or you’ll be getting some back in retaliation – this doesn’t hurt, some 1.5K ranged attack (while you’re on your boat) but it’s better to not cop damage at all, if possible, as your healers would appreciate it.
Fun things to do while in this fight:
1. Just as you’re about to jump back on your ship after killing the enemy mage position yourself between two riflemen , select your landing target and as soon as you’re in the air Thunderstorm. You’ll get some mana back and do upwards of 15 k dmg if you’re lucky enough to hit 3.
2. I’ve never actually tried this but you can leave your fire elemental on the Alliance boat, in the furthermost left corner. You want him there otherwise he might wonder up to Muradin and he won’t be happy about having a big ass fire thingy wondering about on his wooden boat.
Earth Totem: Stoneskin. It will help everybody and it’s the safest choice.
Fire Totem: You want to go with ToW on this one unless you’re trying the Fire Elemental thing mentioned above. Searing might also be a fun choice but it always chooses a random target and might end up shot at by a rifleman.
Water Totem: Unless GBoW is on the table, really, really go for Mana Spring, otherwise Healing Stream.
Air Totem: Wrath of Air, plain and simple
The difference between the 10 man and the 25 man version is in the number of cannons available to your side (2/4) and the HP of the mobs.
