"I like slings. I'd like to change the normal slings, but unfortunately I can't remove the no-str tag from it. I can, however, make new weapons... and I've always wanted to see Jotun Slingers. So in the 0.50 version of the Slingmod, I replaced Jotun Hurler with Jotun Slinger in LA Utgård. If #clear command is added for weapons, I'll release a 1.00 version that changes the normal sling."
Jotun sling deals -2 points of damage (so 18 after strength of 20...), with range 20, precision -2 and 10 shots per fight.
EDIT
Sombre has put together another version of the Slingmod. It changes the slinger units in the game to use the new, improved sling. It can be downloaded from
this post later in this very same thread.
