I used 2 elixir's to beat the Long Gui. Summon knocks him to the floor and then just enfeeble and dmg him, when he gets up use elixir and summon again took me 4 minutes.Seeing as you have the guide, can I ask where I can find the following:
Fire, Lightning, Wind & Earth Charms.
if I sold them (which is possible) then I guess I cannot do the all weapons/accessory task.
I just have:
-Long Gui (Almost beat him, he seems pretty easy with 3 maxed out characters)
-All weapons/accessories (not bothering till I can figure out if charms are still obtainable)
-All 5 star missions (shouldn't be too hard, I only have 20/64 I did not manage 1st time round)

The all weapons/accessories trophy only requires you to of had the item at any point in time so you can sell or dismantle whatever you want and you will still be able to get the trophy.
. I beat him yesterday anyway. Knocked him down once with a summon and once manually defeating his legs. The trick, for me, was using Fangs highwind attack. During Stagger it can take out 90% of one leg or 1.2 million damage on Long Gui, when he has been knocked over.

Now to complete all those Cie'th stones and max out the Crystariums!
