restarted, atm about the best i got is feather token, so 109 in all stats, makes a good foil,
on maid, who has mostly even stat boosts, having sp 90%, res and hit at 105%, rest at 100%.
equipping the all stat things for ease of measuring, equipping imperial seal as a base, the +109 feather token gives 113, so with 7 and 109 together only gives 4 extra points, probably all from FT. 3.3% seemingly
devil ring at 49, plus feather token is 114, giving slightly more.still like 3%
all three together is 119, 5.7% ish.
weapon too is 124 124 on weapon not increasing it
0 + 7 + 49 + 109 gives a bonus of 15. evenly divides to 11%.
using speed on weapon, feather token is saying 129 now.
119 + 7 + 49 +109 gives a bonus of 20, 14.2%
so, at a guess, the same bonus might add like 3% ish per same bonus, improving a bit for multiple same bonuses.
would be better if i had higher accessories but atm, this is the best i got.doesn't help that the imperial seal is probably getting shit for dick to actual stat gains from it. though amusingly since the bonuses show up in the changed stat thing, with the +7 bonuses i get from my all 4 gear at the end, if i'm equipping the seal last, it looks like it goes from +7 to +14. its still just seven from imperial seal, but since the other stuff's bonus stats come on, it just adds it to this total.
