Did all testing as galka war/, naked, using only a sword (buccaneer's sword from the caskets in yuhtunga, was the only weapon I had on hand that I could use at 35 and I didn't have merits in). No str merits. (used the lag job change glitch to remove my subjob), and based my initial numbers off of (I assume byrthnoth's) the numbers from BGwiki

said testing is uniform up to a point. 35~64 looks fine, but the fact that the table wasn't balanced after that bugged me, so I started testing at level 61 on the basis of how prior to 60, the % increases every 4 levels.

**The results also happened to prove that war gets Attack Bonus II at 91.**

* level 81 is the high-ball result that prevents 8.9% from working (81 would have 363 atk if so)

Warcry's boost does seem to plateau after level 73, like shown in the above link, I've just cleaned up the mess between 61~72, and with that cleaned up it should be a lot easier to figure out the equation behind warcry's %, but:

previous testing indicates:

35~36 13/256 (5.1%)

37~40 14/256 (5.5%)

41~44 15/256 (5.9%)

45~48 16/256 (6.3%)

49~52 17/256 (6.6%)

53~56 18/256 (7.0%)

57~60 19/256 (7.4%)

My testing shows:

61~64: 7.7% (20/256: 7.8%)

65~68: 8.1% (21/256: 8.2%)

69~72: 8.4% (22/256: 8.5%)

73~76: 9% (23/256: 8.9%, and my numbers indicate that 8.9% doesn't work)

I did some quick checks with 35~40, which held true to the previous testing and were enough to convince my lazy **** not to check all the way from 35 to 95, but it may be worth looking in to. My gut says that it probably isn't using /256 but rather /512 or /1024, but I'm out of mathy happy fun time minutes for today, so I'll have to actually sit down and record pre/post warcry attack from 35~60 some other time, probably in a day/week/month/whenever I remember. Until I get that done, though;

All percentages done via floor(1000(n/1024))/10 (read: dropping everything after the tenth's place, because SE loves flooring and hates rounding)

35~36: 13/256 (5.1%)

37~40: 14/256 (5.5%)

41~44: 15/256 (5.9%)

45~48: 16/256 (6.3%)

49~52: 17/256 (6.6%)

53~56: 18/256 (7.0%)

57~60: 19/256 (7.4%)

61~64: 7.7% (79/1024 = 7.7%)

65~68: 8.1% (83/1024 = 8.1%)

69~72: 8.4% (87/1024 = 8.4%)

73~76: 9% (93/1024 = 9%)

The last result is the outlier, but given my numbers it could simply be a much smaller % increase after 73, rather than a flat plateau, especially given that the number that prevents 8.9% is 81, a border number on a set of 4. As such, it would be more like:

69~72: 8.4% (87/1024 = 8.4%)

73~80: 8.9% (92/1024 = 8.9%)

80~96: 9% (93/1024 = 9%)

but the results for level 84 prevent it from going any higher than 9.0% (9.1 would have given more attack), so I'm not totally certain. It may just be that they added in an extra kick to it since it's the cap.

I'll see if I can't figure out an equation based on what I have, but if I can't I'll definitely get data on warcry values from 35~60 within the week.
