hi,
Related to the topic of casting a ritual, I'm in need of clarifications and do not find anything in the core rulebook, nor by a quick research on this forum. Apparently, "ritual casting" brings too much results and because of the slow forum these days, it's a pain in the ass to read all those 126 pages of results.
- Can someone remind me if there is something in the RAW about the moment the vis is spent when you cast a ritual spell?
More precisely: you start casting the ritual; do to the vis immediatly disappear, or only at the end of the 15' per magnitude of the spell casts only?
-
and related to the same topic, if you decide to stop casting the ritual, is there any sort of circumstance, like let's say, failing a concentration check while casting a circle/ring spell?
-
do you roll at the start or at the end of the casting time (example: you have special circumstance "day" (which may also be a "cyclic magic positive"). You start an aegis level 40 (2h casting) 1h before dusk, and it finishes 1h after dusk. Special circumstances do apply or not? [noble's parma on the special circumstances/cyclic magic positive applying on ritual spells.]
For question 1 I have no clue; intuitively, i'd say end; for 2 I would have said no. 3 I'd say at the end since I seem to recall that when you have slow caster, your roll at the end of the 2d round.
But my haste to answer in that way is what drove me here to ask fellow players. I may miss something, somewhere and I think there is much more in a lot of players' head than in just my own.
Context of the question : imagine there is an aegis spell on your covenant. Your enemy plan to replace this aegis by his own; in our saga IRL another SG said (and that's what I'm evaluating now) that at the moment he starts casting his own aegis, our own aegis is dispelled (with maybe no malus for casting his own, if the roll is made at the end since the other aegis is gone at the start).
My point would be that if the vis is spent at the end, and if there is no consequence for stopping casting a ritual, that rule is gamebreaking.
It remains dangerous/tedious at least if the vis is spent at start (because we also house rouled that to dispell a Ritual, you need a ritual and so, using vis for a PeVi or vis for a ReVi is not much changing... except that the ReVi is more useful to you than the PeVi) and there is no consequence.
If there are consequences, it would depend of those. If this is a botch roll with as many dice as vis involved, it may be okay because no magus would risk 1+4 or more botch dice in an unamical environment, I think per principle (exceptions may occur).
But if you are able to start an aegis, thus cancelling another aegis, then stop and not spend the vis... aegis are as good as useless in serious situations. (Especially if you are a "normal" magus confronted with a Marched one.)
I'm assessing that house rule checking these questions, because discussing that first house rule would require me to have evidences of gamebreaking situations it creates. And before bringing the topic, I like to know more than just my own impressions or feelings.
