A Portal of Singular Direction ReTe80
R: Arc, D: Year, T: Ind, Rutal
As Hermes Portal but goes in only one direction, and therefore does not require the timing of two portals to be coordinated, and can be affected by a single magus.
Aegis of the Soldier's Hearth ReVi 50, 40, ReVi 30, ReVi 25
R:Touch, D: Ring, T: Circle
As Aegis of the Hearth, final effectiveness is determined by subtracting modifications for range and touch, in this case 3 magnitudes, for a final effectiveness equivalent to an Aegis 35.There are notes that recommend this spell, or similar spells be cast by junior magi and they invite senior magi into the Aegis, because spells over 6 total magnitudes do inflict warping, unlike Aegis of the Hearth.
There are apparently three texts for rituals that appear to follow the pattern of Characteristics of the Heroes. (Mental) Characteristics of the Self CrMe55, and are a R: Self, but otherwise identical to the spell outlined in Houses of Hermes: True Lineages, Presence is the missing text. While the description on the text appears straightforward, the instructions make no sense according to Magic Theory. This texts appear to be flawed or incomplete, despite the title. (Need to unlock this Achievement, in other words)
There is another text that is unlike any Hermetic spell.... It's reasonable to presume it is the ritual of the specialized ward protecting Apollodorus's lab. Consider this another achievement to unlock.
Other texts exist, including several other tractatus and one summa each on Philosophae and Artes Liberales, L5Q10.
