I have suggestions for extra skills
Just want to see what others here have to say about them

<<Sai>> - unlocked by training the <<Dagger>> skill
<<Double-head glaive>> - unlocked by training the <<Two-handed assault spear>> skill
<<Swim>> - unlocked by completing a quest on the 4th floor (Helps non-swimmers swim with system assist and faster swimming with this for those who can swim)
