Awakening a one eyed face upon its stomach. Now the Fire Giant will roll around and will cast more Giant’s Flame incants, capable of summoning pillars of flame or erupting magma rocks from it’s stomach’s mouth.

He can use this to teleport behind the player or warp into the sky and crash land upon the player as well. Additionally he gains one of his most infamous attacks. The ability to control his fire and turn it into a focused laser beam capable of nearly one shotting you. The ideal way to fight Placidusax is to stay behind him as he sits in a more low down posture unlike other dragons.

She is capable of summoning black holes and fleeting microcosms. She can also shoot lasers out of her finger like head and summon small finger creeps.

Midra, Lord of Frenzied Flame

This was fruitless however as Midra then rips off his head and finally becomes one with the Flame of Frenzy. Midra will use Frenzied Flame incantations along with the greatsword that had once impaled him to attack the player. Midra fights in a very elegant way, floating around and gracefully attacking the player.

Best way to combat Midra is to stay close as he will do less of his ranged attacks that are devastating. While staying close, dodging his sword swings will allow for openers.

Bayle the Dread
BAYLE THE DREAD. Nothing more than a malformed cannibalistic dragon. He is the reason Placidusax had lost his other two heads and was a betrayer of the dragons themselves.

Using a broken wing with exposed bone as an improvised spear or sorts. Bayle can breathe a mix between fire and lightning, being able to deal more damage than other dragon breath attacks.

After crashlanding Bayle will be more powerful, being able to super charge his previous attacks and have now attacks such as his own improvised lightning spear and a beam attack from sky high. Bayle’s aggression can be his weakness however, as usually he has good openings for attacks. If you do need some moral support though. There is a man you may encounter on your way to finding Bayle, and let’s just say he has a deep hatred for this thing.

Romina, Saint of the bud
Romina, Saint of the bud was one of the many results of Messmer’s crusades. After the church she inhabited was burned, she discovered a divine element that allowed her to commune with the scarlet rot, additionally her body transformed with her lower half turning into a half centipede, half scorpion hybrid. She attacks via her polearm, and both ends of her lower half, capable of chaining the attacks and following up each attack successively. Second phase begins when she begins to float up, summoning a load of rotten butterflies before exploding them. Romina now uses her butterfly wings to gracefully fly around the arena, slicing with her polearm and leaving behind rotten butterflies. Romina is best fought with precaution. Stick to her sides and do not engage if you are uncertain of a safe recovery.

Putrescent Knight
Putrescent Knight is a mass of putrid flesh merged onto a skeletal frame. It wields a massive, curved cleaver and rides a horse made of the same mass. In first phase it will mainly swing its cleaver and charge at you with the horse. Sometimes he may also throw the cleaver at the player from a distance, to which it will boomerang back towards the Knight. In phase 2 it begins by congregating a mass of putrescence around it as it rises upwards, shooting masses of putrescence burst out it’s back and circulate around it. Causing a ring of ghostflame to push inwards, damaging the player unless they jump. Phase 2 is similar to phase 1 but just that it now shoots these putrescent masses at the player. The best way to fight the Knight is to, once again, wait for moments after it’s attacks, the Knight has incredibly long down times during attacks.
