GS:tLA - Star Magician in 2 turns (direct after reunion)

After doing some vids for the other bosses, here's a vid of the dreaded Star Magician. Because this boss is accessible right after Isaac's party joins I decided to handicap myself in this battle by going here directly before Magma Rock. All party member levels less than 35 and only 65 Djinn are available (and that means no Lull this time round). There are three important facts that one needs to consider:
1)Agility is key in this battle as Star Magician and ball are roughly at 270 AGL. That's why Isaac & Felix are in Ninja class, to keep high AGL and free up as many Venus Djinn for Haures as possible. Next equip Ivan & Sheba with AGL increasing items. All their Djinn are on Stand-by so they'll need some boosts. The Elven shirt (GS1 import) works wonders here just as the Tomegathericon (as demoed on Ivan), because the Dark Mage ups AGL to 140%.
2)4x Haures + 1x Eclipse is sufficient to fell the Star Magician in five attacks, given that you prevent the Guardian ball from casting "Guard Aura". We all know that "Guard Aura" is also used with increased priority, but if you use Venus Djinn Ground/Petra who are also used with increased priority you can prevent the Guardian ball from doing anything! The only catch is that the caster, in this case Ivan, has more AGL by a safe margin than the Guardian Ball (I prefer have Ivan on ~300 AGL, which again is feasible with the Elven shirt & Tomegathericon).
3)Jenna's AGL is a don't care as Flash (damage/10) will be unleashed with increased priority as well. If you do happen to have Lull you can use him instead, just make sure Jenna is slower than the other three members, but faster than the Star Magician. Lull is still preferred, as the Magician might conjure up a second Guardian ball, in which case you might run into a problem the following turn.
By upholding both these considerations the Star Magician can be defeated with little to no effort. If you have some issues with the AGL you could continue on with the game and return here after gaining some more levels.
