There will be no Elemental affinities/enchants I believe. This is more so because there is no magic in SAO. Undead Floor will probably be a theme later
A lake/water type floor will probably come later too
Not sure about possessed/living items ....
Chef profession = cooking profession so yeah
No, won't have anti-durability loss enchantments - just use the increased durability - similar - don't think players could immortalise items, needed to keep repairing
Making NPC guilds, so there probably will be some conflicts
Possibly will do missing person hunts
Combo skills with other players .... probably just switch with party members in the sword skill and seems like an ultra combo or something?
