Do raid mobs get haste effects from items in there loot table if it’s currently an item they will drop that kill? For example the dragons with the haste cloak. If when engaged that cloak is in their loot will the dragon be haste’s during the raid?
No. Non-pet NPCs don't get item haste on TAKP. https://www.takproject.net/forums/index.php?threads/11-20-2017.10393/#post-58163
Interesting. When I was camping the FBSS a few years back it always seemed like the frenzied ghoul was swinging faster when had the fbss.
