Other advantages for the Red Rider.
- Knights are a type of troops, so Warrior of Fog is more likely to be directly applicable to summoning one.
- Traits in general make spell development possible//easier/better IIRC. Mathilde's Knoght trait may apply here.
- Mathilde is developing skills for how to deploy knights on the battlefield.
- The Red Rider appears to be corporeal and has hands, so may be able to pick things or people up and carry them.
- Being corporeal and large, the Rider can act as a physical obstacle to block choke points or impede enemies. Being mostly immune to non-magical damage means that it can block them for a long time.
- The Red Rider is likely to move a lot faster than the Whispering Darkness; which may be useful for scouting and carrying messages, or when running down escaping enemies. Given the likely limits on summoning time, being able to move faster makes them much more useful as fire and forget weapons, as Mathilde can summon them from further away before sending them in.
- The Red Rider has a human shaped body (on top of an equine one). That means it may be easy to teach other skills to, such as scouting.
- The Red Rider can vocalise, as it can laugh, so it may be possible to teach it to speak, which would open up a whole lot of possibilities. Even if it's not sapient simply being able to repeat things others have said could be very useful.
- In many scenarios having a knight escorting you is a lot more low key than having a writhing cloud of darkness doing so.
- Binding multiple Riders stacks in a much more obvious way than binding multiple Whispering Darknesses would, giving more option value.
- On the archetypes I mentioned in my last post, if cultural perceptions of what a knight/mounted warrior is do influence the nature of the Rider, then it may be easier to teach Riders to work together or with others than it would other Apparitions (save the Hounds). It may also be easier to make the Riders loyal, as that's part of the Knightly archetype. I'd prefer a relationship with an Apparition where they're vassal rather than slave, if they're sapient enough for that to be meaningful.
- Grey Wizards are particularly likely to operate without backup, so having the ability to create it out of nowhere is particularly useful for the College.
What Ulgu spells can the Whispering Darkness imitate? I keep seeing this point raised, but which specific spells already exist that make the Whispering Darkness redundant?
Some of the already Ok-Ed fog spells like ones that are selectively applicable or the corrosive fog one.
