Anyway the Tough Lona kill faster than Sea Witch Nympho Lona especially if you play as Abomination Tough Lona + Halberd because it's like... 100-125 damage per hit if you have only 40 COM stat therefore you can literally kill a whole crowd just in 10-15 seconds same as OP Timid Lona mage that can deal 120+ lightning damage per 1 sec or Fire Spell Book which can kill almost anyone if you have 40 WIS stat (And you also need to remember that there are a lot of things for the mage now that makes mage is kinda very powerful creature with unbreakable 25-30 DEF stat). These are the two strongest builds in the game right now. And if you know how broken the Katana is... weeeelp... you can even deal 300-400 damage per 1 hit.
cdelorme - I found Musket useful for taking out many weak enemies, like rats, or skeletons, where you can outrun them, and the only reason I mention it is because every other AOE weapon you listed either requires Mana Control or Weapons Expert, which was the original problem. Perhaps I haven't played as much at world level 100 to notice the DEF/SUR issue.
Spending 1 point to use a special weapon is not a problem but in any case the Musket has weak DPS and it weighs twice as much as a regular Bow which can be more useful than Musket especially since a Bow hits everyone in path while a musket only hits 1 target and Bow deal more damage than Musket per 1 hold shot + Bow is much safer than Musket because the enemy is thrown back and also slows down.
