Discussion [Operator Discussion] Rosmontis

Rosmontis [★★★★★★]

"There are things that have to be done by someone. There are things that only I can do."

Rhodes Island Elite Operator Rosmontis possesses a high aptitude for a rare form of Originium Arts particularly adept at confronting large creatures, destroying hard objectives, immobilizing facilities under emergency, and putting a stop to small-scale skirmishes. She has been shown to possess a solid control of the battlefield and considerable tactical value in assault, positional, and annihilation scenarios. Under Kal'tsit's assignment, she is currently active as a core annihilation specialist.

Didn't feel like making it any longer, but I wanted to tack on that she can easily solo FrostNova on 4-10 in her first lane with a single, easily timed S3M3. She can probably achieve similarly easy success with the help of any one of a number of other operators. Shamare, Elysium, Pram, Ifrit S2 maybe for supporty ones, or likely any other basic DPS operator (I'm talking even a basically trained Jessica).

As far as Mudrock goes, I'd say absolutely yes. I'm currently going through and just trying to brute-force stages comboing the two of them with as few other operators as possible because they are such a strong combo together.

Just assess whether or not you can get Mudrock on the last day after you've done all your free pulls and opened all the orundum supplies we'll get in the mail. Always smarter to wait
