I recently upgraded my Apocalypse Sword to include the effect of the Sword of the Ferocious Wolf, and I've noticed that for some reason the Ferocious Wolf and Flame Qilin swords share a cooldown. When the Flame Qilin sword is procced, for some reason Ferocious Wolf shares its 4-second cooldown. This means the 30 Magic Power I spent upgrading my sword was completely wasted since Ferocious Wolf never actually procs. This should definitely be looked into, especially considering Magic Power is so time-consuming to get (those 30 took over 2 weeks to get since we can only buy 2 per day). The effect does actually proc if I manually switch over to my Wolf sword, let it get on its own cooldown timer, and switch back to Apocalypse, but it's only a matter of time until the cooldowns between Qilin and Wolf match up again and the Wolf sword stops proccing.
