I don't have any problem with most weapons in the game but this made me lol
Dark bone swords have sp recovery XD
for those who don't know, sp recovery is the fairly useless stat on the stat page that plays a part in how fast your staff/wand charges (I was wrong about this recently so my apologies if I confused anyone).
just to clarify:
sp regenerated is determined by mnd and max sp
sp regenerated on hit is determined by the weapon type, swift has no effect afaik
like this:
sword 4 sp per hit
twin sword 4 sp per hit
odachi 10 sp per hit
bow 3 sp per hit
axe 11 sp per hit
spear 7 sp per hit
staff 4 sp per hit
wand 3 sp per hit
Nothing affects the time between regeneration ticks
so, I think the devs forgot what sp recovery does.Good luck charging your TS :P
edit: typo -.-
edit 2: forgot odachi D:
