Last night we had little fight between players about discovery and breakthrough. Its about seasons. First season you make Discovery, then next season you make stabilizing: gain warping( if any) and breakthrough points. After stabilizing, next season you need to make new discovery and then new stabilizing. Or you just make stabilizing next season after first stabilizing.
So main question is about seasons:
Discovery Stabilizing, Discovery Stabilizing.....
or Discovery, stabilizing, stabilizing, stabilizing?
So "lost the chance to stabilize that Discovery" by its context refers to the stabilization process of one season only.
New season, new try - unless some unspecified "dire event", in detail adjudicated by your SG and likely derived from an ArM5 p.109 Extraordinary Results Chart botch followed by a very bad result there, stops your attempts. If e. g. your lab blew up or your covenant caught fire last season, you cannot spend this season for another attempt to stabilize your Discovery, hence have to abandon it.
If you read the entire HoH:TL p.28 Stabilizing the Unknown and thus have the context of all the quotes given here, there is no contradiction. Jabir likely just skimmed the text quickly and misunderstood it, which can happen to everybody and with any text.
You may think so, but I'd say that "you have lost the chance to stabilize that
Discovery" is pretty categorical and in direct contradiction to "should an attempt at stabilizing a Discovery fail, you can repeat that attempt". I'm not sure which version is better.
It's probably the most confusingly written section of any AM5 book that I know and was thoroughly, but apparently not thoroughly enough, corrected in the errata years ago. We still have disputes on how discoveries can be taught to others after reading the section.
Apparently, reading in context is not really a forte of some role-players. So let's for once as an example copy the entire paragraph:
The entire paragraph addresses what happens in the single stabilization season, with a single stabilization process. So "the chance to stabilize that Discovery" is the one accorded by that season - not any chance you ever can have: that would be at the verrry least "any chance to ever stabilize that Discovery".
From there we can read and understand:
This phrase addresses stabilization season by season.
In any case, isolating a phrase from its context and then quoting it as "the truth" is not a sign of reading literacy. Just imagine somebody claiming, that the above sentence "Ignore any beneficial result you might roll." applies to ArM5 in general. Isn't it from the rules, and "pretty categorical"?
Game rules should not have to be "analyzed in context". That is an issue with Ars Magica, in part due to the complexity of the system, but moreso in part because it was written mainly by fans and amateurs. I was one of them. I am painfully aware of all the flaws my few works have.
