TL;DR: Have Gravity, don't not have Gravity. Not-Gravity sources do 10-20% damage at best. Here's my test run with bad team: Couple more: First run of this, so setup wasn't entirely ideal. Most of my gravity units are underleveled, but had just enough to manage the clear. If Primordial Dragon King wasn't bad enough, this is yet another DPS check fight. The difference is the only reasonable source of damage is Gravity, everything else is reduced to 10-20% depending on source. Rotation: Glimmering Portent -> Photonball x2 Holy Breath, Area(1) + Null Healing (All) At around 40(?) percent 420K HP, RDK will leave the stage. The following three turns will summon Dracofeathers. These are mostly harmless, using only Breath, Area(1). It is imperative to take all of these out, however, as the 4th turn RDK returns to the field and consumes any remaining Dracofeathers, also summoning two Holy Starwhips. Upon his return, RDK will flee after 5 turns. Each Dracofeathers he consumes will reduce this counter by 1. This is where you need to use your Augments, Impairs, PP, etc. to destroy him before he flees. Post-Dracofeather rotation: Holy Breath, Column (1) Holy Breath, Row (1) Holy Breath, Column (1) + Nullify Healing (All) Holy Breath, Row (1) Flee Sparklewhips will use a Photon skill orthogonal to what RDK uses. They use a MDEF debuff on the Nullify Healing turn. PP Generation is very slow in this fight, so it is helpful to keep a mostly full bar, perhaps using a PP to push him as far as you can into the Dracofeathers phase, or if you need the extra boost to clear the Dracofeathers. http://terrabattle.wikia.com/wiki/The_Resplendent_Dragon_King http://terrabattleforum.com/threads/terra-battle-4-0-0-update.10663/page-19#post-108438 Handy tidbit: If you exceed the Dracofeathers phase threshold while RDK is targeting Glimmering Portent, he will use his turn for Photonball instead of levitating. This allows an extra pincer before he leaves. If damage is tight, then aim to take advantage of this extra turn.
