Well, I dunno if the KQ's second form can be hit with melee occasionaly, or if this was a bug, but a partner and I were killing with Veracs. Someone else on a slayer assignment, with armour, whip, black mask, tagged along with us to get good slayer XP on the kalphite workers that pour out after the KQ is killed. Well, the thing I wasn't expecting was, he actually dealt the most damage, and was hitting a lot of 30+ hits with his whip on the second form. I'm assuming he was hitting well with the whip because of the mask's 15% attack and strength bonuses, particularly the attack bonus for hitting at all.
