I have the server record for Titan... 8)
I've said there are 2 rules for summoners...
1. Panic
2. Run away :lol:
And this applies perfectly to the summoner battles...
I used boiled crab because it gives good vitality and defense ups.
I make pineapple juice, so I used that in the beginning instead of Yagudo Drinks.
I brought 2 Ethers/Hi-Ethers. (They're about the same price and Hi-ethers are in stock more often, the only downside to the Hi-Ether is the extra long cast time)
I also brought a few Hi-Potions, but if you're following the 2 rules, you shouldnt get hit very often, and can most likely use Cure instead.
Step 1. Get some high lvl person to buff you up with Protect and Shell. It only takes a few minutes, and you shouldnt be rushing anyway, so take the time to get it. After that cast Aquaveil on yourself, eat the crab, and jump through the protocrystal. (You can try and get bar-(something) from them as well, but its been my experience that it'll run out before you get to them no matter how fast you are)
Step 2. Hit the ground running, and run all the way around the bend until you get to the last crack in the rocks, right in front of the last upwards slope, and you should be able to see the Avatar now, abeit far off. Drink a juice, (I used pineapple to start with) start casting Carby, and the avatar should aggro.
Step 3. For the moment your job is done, RUN! The avatars have a habit of starting off their fights with a BloodPact/2Hr. And those are bad. So you should leave all that to Carby and run back to the starting crystal. (Be sure to watch Carby name, if at any point in the fight it disappears, recast him, gauge what side of the arena you're on, and run to the other side.)
Step 4. When you recast him on the other side of the arena, Dia that fool before you run to the other side. Its not much, but people have lost fights over less HP.
Step 5. Repeat step 3 until your MP is around 80-100. When the avatar starts heading to your side of the arena, cast carby, drink a yagudo drink, and Astral Flow yourself. Ready Searing Light for when the avatar arrives on your side, stand somewhat close and cast it. (The reason for not immediately running is the hate transfer to you while Searing Light is being readied, as it is an AoE effect, the avatar needs to be as close to carbuncle as can be.)
Step 6. If you drank the Yag Drink, Carbuncle wont immediately disappear, so run back to the other side. Your MP will slowly tick up, and you have something of a choice at this point. You can use an ether, and wait 60 seconds before attempting your second searing light, or you can just wait for your yag drink to refill your HP as much as possible. (All this food gets expensive, so I try to save gil where I can) Wait until you have a new carby cast, the avatar heading towards your side of the map, and have 44 MP before proceeding to step 7.
Step 7. Cast your 2nd Searing Light on the Avatar.
Step 8. Rejoice in the avatars death.
Hope this helps a little bit. Watch out for Ramuh and Shiva, they like to paralyze. If it happens, spam Paralyna and pray. If you get interrupted during your first carbuncle cast, then you are standing too close.
