It's best used on jobs who have two or more and frequently use abilities that have 20~30 second cooldowns, such as the Dragoon and Dark Knights. Namely jobs that without a doubt will not conserve their abilities.

I don't think the Spear should be used on a Bard at all, because their trait resets their already short CDs, meaning the Spear card would have significantly less impact on them.
I also don't think Spear is good for Summoners, Black Mages, Warriors, and every healer except yourself.


Extended Spear is the best version. Expanded Spear is the worst.
