I heard that, when Piko uses Call Beast on his Beastmaster he summons 150lv versions of Nidhogg, King Behemoth and Aspidochelone. All 3 of them at the same time.
Back when he was young Pikohan casted 1 Raise in Valkurm Dunes and all the Newbies in the Zone came back to life while all the Undead died and dropped Magicked Skulls on the floor.
Since I /kneeled before Piko, he instructed me how to improve my MNK, I now do at least double the damage of 2nd person on parse. Except when Piko is in ally, then he does 100% of damage of course.
