There might also be a semblance of sound manipulation. The character could use it to create deafening sonic blasts to attack enemies, or use sound waves to detect hidden objects or people. They could even manipulate the pitch of their voice to imitate others, which could be useful for things like spying or tricking opponents in the fanfiction.
One interesting semblance could be the ability to manipulate time on a small scale. She could slow down time for a brief moment to dodge attacks or speed up her own movements.

It also adds a layer of psychological drama as characters have to be constantly on guard against mental intrusion.
One interesting fanfiction could be 'Jaune's Dual-Edged Destiny'. In this, Jaune discovers a weapon that can transform into both a sword and a shield with unique abilities. It adds a new layer of strategy to his battles.
One interesting idea could be a crossover of different timelines within RWBY. For example, characters from the past meet the current ones and have to deal with the differences in their worlds. Another could be a crossover of different teams in unexpected ways, like Team RWBY having to team up with a rival team to face a common enemy that is more powerful than any they've faced before.

Some might be interesting for their creative interpretations of the RWBY world's magic system. They could introduce new spells or ways of using Dust in really imaginative ways, which makes the reading experience quite engaging.
One interesting RWBY IT fanfiction could be one where the RWBY characters encounter Pennywise in a strange alternate dimension. The RWBY team might have to use their unique abilities, like Ruby's speed and Crescent Rose, to combat Pennywise's mind - games.
Well, a plot might involve Team RWBY traveling back to the time when the first Huntsmen and Huntresses were being trained. They could get involved in the early development of combat techniques and weaponry. Maybe they end up influencing the way things are taught, for instance, introducing some of their more modern strategies. Or perhaps they go back to a time when a powerful relic was first discovered and have to protect it from falling into the wrong hands, which could change the entire future of Remnant.
Ruby would probably be thrilled to see all the new storylines. She loves adventures and the fanfiction could offer her a whole new set of them.
One interesting concept could be the use of hypnosis to unlock hidden powers within the RWBY characters.

Also, it could be used in a more positive way, like hypnosis for healing psychological traumas that the characters have endured during their battles.
One idea could be a crossover where a character from RWBY gains the powers of Dishonored's Corvo. They could use the blink ability to quickly dodge attacks in battles against Grimm.
