Ex Containment bay S1T7 with Summoner?

[Mattski3]

Hi, I'm working towards getting the Firebird mount and I managed to get 5 out of the 6 Lanner mounts required by soloing Ex Duties with my Summoner.

I just need one more which is the one you get in CB S1T7. I always get to the part where the arena fills up with the green light, at which point you need to go right up close to him to avoid, but I always die at the part where he shoots you several times while this is happening. Is it possible for a Summoner to survive this and if so, how? Or do I need to use a Tank class to solo this one?

I did it with my SMN before, and I think for me the key was to have Phoenix at the ready for when that time came. It gives you a passive heal that keeps you alive just long enough to kill him dead. Being at max level helps, too. Tried to find you on the Lodestone just to see what level your SMN was but I couldn't find you, so I can't really give any other advice besides making sure you are max level. Failing all of that, yeah being a tank makes soloing HW trials a heck of a lot easier.

5 out of the 6 ... I just need one more which is the one you get in CB S1T7.

After ARR, each EX trial set is 7 mounts, so you're missing two.

Take Vahlnir's advice and make sure you hold Phoenix for that part. Also have both charges of your shield up and be ready to refresh it immediately after the first shield goes down. If necessary prioritize reapplying your shield even if it requires you to drift your GCD. Even RDM at that part has to MBarrier and stop attacking to spam Vercure. Since Physick isn't even worth mentioning you'll have to rely on Phoenix's regen and Excogitation-ish. If you can't get it on the first try, don't give up. Drag out the first phase before the adds so that you can make sure 3 minutes pass before you die (3 min is the minimum time to build an echo stack).
