I actually must retract my previous statement as there was an interesting discovery concerning these gloves.
"Enhances Sekkanoki" Actually gives you a TP bonus similar to Hagun. The +1 have been estimated at TP Bonus+50 but the +2 shown here could have a higher effect.
Paired with other TP Bonus+ gear such as the WOTG reward earring could prove rather useful and since its +10 STR vs Heafoc's +13 STR... these actually may win.
The "Enhances Sekkanoki Effect" on these gloves essentially uses your current TP as the modifier for your next WS, despite the WS costing 100 TP.
For example, WSing at 230 TP with Sekkanoki up will grant an 130 TP bonus to that WS. It's unknown whether the Kote need to be equipped just for the ability or for the WS as well.
This does not affect Aftermath effects though, WSing with Sekkanoki even at 300 TP will still only grant a level 1 Aftermath.
A very sexy piece for Fudo when you Sekkanoki a light skillchain but stick to Heafoc Mitts for everything else.
Yea these might actually win once every 5 minutes.. that's if you're one of the SAM's who actively build up your TP so you can say 'Sekkanoki; Don't WS' (therefore making other DD save and waste their TP) purely for the satisfaction of saying 'OMG did you just see the DMG I just did?! I did over 9000'.
At the start of fights or where you're able to store the TP these are pretty mint, but other than that, I won't be +2'ing these anytime soon.
