Is Soul Destroyer actually good in this server? They're too weak once you get your 3rd class skills on other servers. Is that certain One-Handed Sword the Magical Blade [3] by any chance? They still have no business being in the artwork for Crusaders and Royals Guards though. Sword Mastery affects Daggers as well so it's not really trash for Rogue classes. And there's always the Elemental Sword gimmick...
SBK is endgame viable here and 1h swords are the weapon of choice for it (main hand), cross impact and partially counter slash on, plus any melee skill on SC. Genetics also make good use of them in PvP situations and Naght Sieger swords are pretty good for mado Mechanics. It is true that they're kinda phased out for swordies but at the same time we have an entirely worthless weapon type; 2h spears.
Off-topic: How does the built-in custom bonuses for skills in-game stack with outside bonuses to the same skill. For example, the bonus on Wind Cutter with Two-Handed Swords and the set bonus of the Peuz set. Do they stack additively or multiplicatively?
The built-in bonus for those skills changes the base formula instead of adding damage, item bonuses apply on top of that so there's no stacking involved.
