First, a general one about the class formats; while the stat columns, I am assuming, are meant to reflect that stats' current rating, like in standard D20. Is this also true for the "Bonus" column, or are those enhancements meant to be cumulative? For example, does a Whm get a total bonus to WIS of +6 (at 48th level), or +18 (the cumulative enhancement)? I ask because the Crusader table has some of its higher level bonuses actually going down, then up higher again (such as its "armor" bonus). Or, is it dependant upon the type of score the bonus applies to? (IE, attribute enhancements are linear (WIS +6), but other stats are cumulative (Armor +18 ).
Second, is it you're intent that spells cast by high level casters are unavoidable even by other high level (even higher level) characters? For example, assuming even pathetically average ability scores, a spell cast by a 50th level Blm (or Whm) cannot be avoided even with a Resistance roll of 20 (assuming we are ignoring the "automatic" success of a "natural 20") by any of the classes published so far. Crusaders seem to be the only ones capable of avoiding their own magic on a 50% margin; everyone else is doomed to failure.
Ok.The "bonus" colum lists the current rating
Ok, but then won't that imbalance things unduly at the lower-level end of things, with just about every spell being avoided by even lower than average D20 rolls? For example, our struggling 10th level Blm (yeah, I know, not that low level, but bear with me) now has a MAGIC of 6, granting an MC of 6 (remember, he's none too bright for a BlmThat "10 + Magic + Attribute Modifier" should probably just read "Magic + Attribute Modifier."
Glad I could help.Expect the jobs to get a universal RES bump. It's easy enough to do, but it's definately something I wouldn't have noticed without some help.
Which is entirely appropriate. Each class should have some level of variance in how it can resist magical effects. Remember though, as I am sure you will, that the WIS based casters (like Whms) will have an inherently higher RES than the job tables will overtly indicate thanks to job-based stat increases. Too bad about those poor black mages though...Still, you'll find the Thief saving against spells about 1/2 the time, Crusaders (and White Mages) maybe more like 3/4ths....Black mages maybe closer to 1/4....
Keep up the good work, and we'll even make allowances for the extra time your um, "research" will take in reveiwing the new FF12 material.
