If people were looking for more proof that TP Bonus and WS Damage weapon +2s work the way they're rumored to, these Aeolian Edges were all done against Wild Rabbits on DNC/SAM with Meditate + 2FM Reverse Flourish (100 TP):
* Twashtar/WSDamage+10% Fusetto +1 : 408 Aeolian Edge
* Twashtar/Nothing : 408 Aeolian Edge
* Twashtar/TP Bonus +100 Fusetto +2 : 511 Aeolian Edge
:: CEILING((408-32)/2.75) = 137 base damage
:: FLOOR(137*3.5)+32 = 511 damage with 100 TP Bonus in offhand
* Martial/TP Bonus Fusetto +2 (with +15 DEX in gear) : 580 Aeolian Edge
:: 137*4 + 32 = 580 with 200 TP Bonus total
116 TP, Sekka->Aeolian Edge
* Twashtar/TP Bonus +100 Fusetto +2 : 408 damage
:: So it interacts with Sekka the same way Martial Knife's TP Bonus always has.
