Raid Boss Spawn Help

hi all,
i'd like to know if there is any tool/way that let me know if a raid boss is spwaned or not where ever i am,i play on a private server ct1 and even if i spend days looking if a big boss is spawned,someone else always come before me...so ...
i suppose there is a way.

any idea?

thx. :)

there is no way. every 'Big Boss' like u call it, like Anthi, Vala, BAium, etc has a fixed respawn timer, like 12hours or something ... u just need to know when it got killed, and u know when it will respawn.
