The rune scimitar is the second strongest scimitar available, behind only the Dragon scimitar. Like all rune weapons, it requires 40 Attack to wield.
Players can make a rune scimitar with the smithing skill at level 90 using 2 rune bars, giving the player 150 smithing experience. It also can be dropped by various monsters such as fire giants or mummies.
The rune scimitar is widely considered to be the most powerful melee weapon in free-to-play servers; its attack speed results in arguably the highest damage-per-second among rune weaponry.
A members-only alternative to the rune scimitar is the rapier for those who are able to complete the Cabin Fever quest; the rapier has identical stats, with the slash and stab bonuses inverted. This makes the rapier better against NPCs weak to stab and a feasible option on Ironman Mode. Another alternative that is considerably more expensive, but slightly better for training, is the brine sabre, giving +2 for both strength and slash. Players who have completed Desert Treasure may also use the ancient staff, which has a higher strength bonus than the rune scimitar and attacks at the same speed, however primarily attacks with crush or magic, rather than slash.
