Topic: There are a whole list of "Boss" monsters that do not allow the proper slayers to work on them. Most of them seem to be the bosses that were created for the Tamer quest. Although Colossus was prior to the quest, it is one of the bosses that a slayer doesn't work. Here is my list of bosses and relative slayer that should apply, which currently none work. @Chris -Colossus - Repond -Land Shark - Reptilian Death -Ophidian Queen - Reptilian Death and Ophidian Slayer -Obsidian Gargoyle - Exercism and Gargoyle's Foe -Two Headed Behemoth - Repond -Anaconda - Reptilian Death -Jungle Titan - Repond Side Topic: When u hit monsters with the slayer weapon that damages them, it makes a white circle animation on each hit (Hitting a lich with a silver wep). Similar to when a player with parry blocks an attack. On another note, Slayer weapons are supposed to drop from its opposite Slayer family: Reptiles vs Arachnid Humanoid vs Undead Abyss vs Elemental All of the boss listed above (from my experience, if someone could prove this wrong it would be great) need adjusted loot table to reflect the dropped slayer, right now they all fall under the default "silver" weapon drops.
I've been using silver weapons for years and I've never noticed this. I've only ever seen that animation on a parry.
