GS:tLA - Doom Dragon - No damage, no rare items, level 47

After looking back to my old video where Doom Dragon is defeated in three turns ( • Doom Dragon - Total Pw... ) without being able to attack the high levels and huge lot of very rare items doesn't make it the most practical run. So here's an improved run which requires only Level ~47 characters (in order to use "Call Dullahan" in the Necromage class; use the tomegathericon) and minimizes the use of rare items.
As shown in the inventory during the beginning no real special items were equiped other than a pair of Riot Gloves for Felix (to boost his unleash rate). Most of the other items are not really that necessary. The Fire Brand and Masamune provide Garet & Jenna enough base ATK to get sufficient damage output with "Call Dullahan" & "Quickstrike".
As it's not practically feasible to get 5000 damage during the first turn (unless you use up all your Djinn for summons); I've changed it to a warm-up round where both Garet & Felix boost their elemental powers and end it with Lull to prevent DD from attacking.
Next Sheba's high AGL allows you to use both Kindle & Forge for double ATK+ boost. I still prefer the Excalibur's Legend unleash, but considering Megiddo is more constant in damage (it always does 3x damage) I've opted for that item instead (during the battle Felix's Venus power maximizes to 200 so that helps too).
In all, the main strat is just to switch Isaac, Piers, Ivan and Sheba to get 2 Azuls & 2 Catastrophe summons spread over the 4 turns. Mia wasn't necessary for this battle, but if the Dragon casts 'Guard Aura' she can be switched in allowing a Boreas + Ulysses unleash. So even with this really weak setup there's still plenty of leeway. XD
