Hammer and Arrow

Thiul wasn't going to keep this attack up forever, or at least change it up before Titus came up with anything to counterattack it. But just as Thiul was performing her last attack of this type Titus stroke back by shifting into his human form. He didn't stop there but shifted just his arm into that of a dragon and grabbed Thiul. His claws dug into Thiul's back leg. Her scales and spikes protected her to some extent but Titus was a fire dragon and his heated claws did their damage. Thiul screeched and attached herself onto the ceiling once more, though just for a second. She shifted into her human form as well, getting out of Titus' clutch. She let herself start falling and she observed the damage to her leg. The damaged tissue that had not suffered from burns would heal fast enough, but the burns were going to last longer and be painful. Thankfully her legs were already damaged so it wouldn't affect her normal life much aside from the pain. And that Thiul could bear, pain was nothing.

Thiul let herself freefall for a moment before she transformed into ice particles and blew over to the wall. Closer to the wall Thiul shot a row of ice spikes on it and they dug into the wall and Thiul landed on them. Her legs wanted to give in but she didn't let herself fall to her knees, not now. Instead without missing a beat she shot six ice spikes as big as her but still fast towards Titus, already preparing herself for his next attack.

Dodging the boulder was simple enough, Thiul simply transformed into ice particles and dispersed from its way. She materialized again on top of it, and stood there watching Titus walk closer and talk down to her. Her legs wanted to shake and give in. Thiul didn't let them.
Titus was right, she didn't have much options. But Thiul had too much pride to give up. She would go down how she chose. Her eyes were ice as she looked down on Titus from on top of the boulder he had hurled.
"It's over? I'm still standing, aren't I? It won't be over until my knees hit the floor. With that, you defeat me, last hammer."
Thiul sent another set of six big ice spikes at Titus. Thiul shifted into a dragon again, and followed immediately after her ice spikes. Her legs didn't touch the floor as she shot herself at Titus, all the while shooting ice spikes and never stopping. Thiul wasn't as good of a close-range fighter she once was, not without her legs. But this was a so-called last stand as she swiped at Titus with the claw at the end of her wing, at a great speed.

Thiul spun around and took the explosion Titus unleashed with her backside. Her spikes and scales prevented the worst damage. She saw him jump, nimble as a cat, but he was not the only nimble one around. Thiul was able to roll out of the way, though she felt some of Titus' napalm stick to her.
The smog made it near impossible for Thiul to breathe and see but she swung her tail, and the big sharp ice spike at its end, to Titus general direction. The heat he was giving out was like a homing beacon that Thiul aimed at.

Almost the whole room was filled with Titus' smog and the places that weren't were not hospitable enough to take cover in. Thiul's eyes weren't suffering much thanks to her second eyelids but the visibility was crap nevertheless. Thiul took flight and put some distance between herself and Titus. She knew it was but a temporary solution but she was trying to buy time.
As Thiul flew farther away from Titus she shot a volley of ice spikes at him from all directions. She couldn't see him but she could still feel him radiating heat. Thiul purposefully left Titus' words unanswered, as they greatly irritated her.

Thiul intended to land somewhere at the edge of the room, near the door, where there was less smog. But Thiul was more tired than she had realized, the adrenaline had kept her going. So her landing was rough and Thiul's legs caved in, limp and useless now. Thiul collapsed and growled to herself, glaring down at her legs as if intimidating them would get them to work again.
"Bad fucking timing..."
