I'll try that next time.

At the moment, I always used shield on a 2 count of flame spike on the designated character and Engulf on a three-count, but it is indeed quite hard to manage. If shield isn't needed it's like 10 times easier. :P

1-1-1-2 normal rotation but when I need shield on one

1-1-1-2-1-1-5-1-1-1-2

That way you dont loose the debuff. The ones not shielding just get a 5 combo pointed Engulf.

If what you say is managable without needing shield, the debuff will also stack quicker which makes the fight not only easier to manage, but also quicker.

So you're saying 3-1-1-2-repeat? I found only 2 combo points for engulf made shielding impossible, but heh, without needing shield, it should work.. Interesting.. >.>
