All 31 S-Grade weapons of Lineage 2 Interlude, by type with their stats. Open an item to see where it drops and how it is crafted.
Having levelled up to 76, we get the right to carry S-grade weapons without a penalty, and here we have no choice left at all, because in S grade there is no division into low and top weapons: what there is, is what we run with. The weapons of heroes are a separate talk (they are S-grade too, no SA goes into them, but each hero weapon has extra properties that more than cover any SA); since only heroes can have them and there is no other way to get them, here we talk only about what can be crafted and obtained in the natural way.
Crafting any S weapon takes a heck of a lot of resources, so we are not surprised that our stocks melt away quickly.
And, strange as it may seem, that is all the S-grade weapons there are. On my dwarf girl I prefer to carry several kinds at once: S duals for mobs, a pike for trains, naturally, and, in case somebody picks on me, some axe without fail (the basalt is the more decent one, but it costs more and needs a shield with it; the DHA is cheaper but two-handed; the main thing is to put the cheeky one into a stun, so judge for yourself). A bow is needed too: it happens that after the stun and a kicking with the axe some cheeky one starts running away fast, and then you have to plant a handful of arrows between his shoulder blades.
The only choice in S grade belongs to mages, and a doubtful one at that: the arcana with the SA for acumen or the Imperial Staff with the SA for empower. I have seen necros in the major arcana robe with an imperial staff, hoping, as always, for a super nuke.
As for sales, the drac bow and the arcana come first, of course, then the HD and the pike; there is demand for the basalt; the cheapest are the fists and the S duals, because the dual swords are made at the blacksmith of Mammon out of two A-grade swords plus ancient adena.
And right away, so that there are no extra questions about the Shining Bow: there is no Shining in the game, neither a recipe from quests nor a drop or spoil of its key materials, and the Primeval Isle gives no reward in keys for it either. All of that is the invention of some free shards, which try in this way to attract players or to earn an extra buck.
