Quake stomp is a buff -.- and yes hes a pld -.- i've seen him do 7k to my friend with overthrow after hes used quake stomp. i've seen the main leader do 13k with overthrow....he so owned me v.v
Fought him in besieged today.Absolutely SPAMS Invincible,foot stomp attack(forgot what its called),and Cure III when he reaches about half health. We all got him down to about 25% health before besieged ended :( really wanted to see him die. On the upside(for me) I got a new most damage taken record after being hit with his Rock Crusher attack for 5,558 dmg while fully buffed. ^.^b
his stomp attack is called Quake Stomp, it sounds like AOE, but it didnt hit me, and i was 2 inches behind him when he used it >.> judging by that, it's either a single target attack, or it's one that only hits people in front of him. also, this guy is NOT something you want to walk in front of when he's rampaging around unclaimed, i did it and got rewarded w/ some type of ranged attack that did 3k damage and blew through Stoneskin and Phalanx. also, it's not a good idea to raise anyone in the vicinity of this guy, cause he'll aggro to you while you're using the spell, that's what i was doing when i got hit w/ the ranged attack. also, he resisted my every attempt at Dispelling his Invincible, and started spamming cures on himself and another NM that was in the vicinity who's name i forget (it was a warrior type i'd say, based on it's weapons and attacks). anyway, that's my experience with the trolls in lvl 5 beseigeds, and the scorpions the trolls bring with always seem to actively seek out the Serpent Generals....except the crazy hume, who always actively seeks THEM out and ends up dying lol :p.
He'll cast Cure IV if he starts getting low, which is annoying...but since he has so much HP anyway, 350 isn't that big of a dent, good or bad. I've also seen him cast Shell III near the beginning of the battle, as soon as he ran in, so I'm guessing he can cast any of the spells that a PLD can...he's just stingy with them.
