Well, our current Ancient Magic campaign seems to take off nicely, with our merry band happily on the tracks of the secrets of the Garden of the Esperides, and later, Eden. Judging from feedback and experience from the first sessons, I've already planned, beside some minor retrospective adjustments, the main goal of the first substantial downtime period. I want my generalist spont specialist to initiate Major Magical Focus (Damage), the Mutable version first, the full one in another later one. Now, since I happen to be much more expert on the details of 5th ed. than main SG and both player and assistant SG in charge for all 5th Ed. rules advice (being a completist buyer and avid reader with a good memory pays ), asking the main SG for advice isn't a fully viable option.
My doubts: my character already has Diedne Magic, Chthonic Magic, and is all but completely helpless at formulaic and ritual magic (Rigid Magic and/or Unstructured Caster). When the mage will grow experienced with substantial Art scores, stacking focus multipliers from three sources (DM, CM, and MMF) to a lower Art x4 multiplier seems rather... excessive, even to a self-awowed powergamer like me. OTOH, I would not like to initiate Major Potent Magic, since as for all fixed bonuses, that Virtue seems me to grow pitiful in value as the mage gains experience, and my character hasn't a magical focus so far.
I have thought of putting a cap so that you can combine focus-like doublings to a combination of two, maximum, something the books explicitly allow (so that you can combine the bonus from the focus with either expending fatigue, or the chthonic bonus, but not both, to x3). I am uncertain whether this should be an official house rule, or a I should give my character a Deleterious Circumstances (combining more than two foci) as an Ordeal. I do not desire a x4 bonus, I just wish to improve to make the character's combat spont effects a bit more flexible and effective, so that substantive combat spont magic can sometimes be used without expending fatigue and/or using the chthonic bonus. A MMF (Damage) seems well in accord with the passionate personality of the character and his non-pacifist background. Or alternatively, I could initiate Major Potent Magic (Damage) first (mutable or not), than a second Initation later to change it to Major Magical Focus (Damage).
Moreover, I guess I should develop the script for such an Initiation by experimentation, since character's present Mistery Cults (Merinita and Philosophers of Rome) do not strike me as particularly likely to have an Initiation Script for MMF (Damage), but I might be wrong. Or to be more precise, a script for the first Initation, to develop the Mutable version of the Focus, then another Initation later to upgrade it to the all-time one. OTOH, that's the lab work and quest I wish to develop in the next downtime slot. I need some good ideas for the script: so far, my ideas have been rather bland: a Deleterious Circumstances (Healing) Ordeal, a Fury or major Wrathful Ordeal, a set of Hercules-like quests (defeat a dangerous supernatural creature from each realm of power, plus a powerful human sorcerer; by combat in one script, by non-violent means, including certamen and trickery, in another), create and destroy a Talisman... any good ideas that would look appropriate in a Merinita or Philosopher of Rome script ? Thanks.
