<p>The best site for that is <a rel="nofollow" href="https://guildstats.eu/bosses">GuildStats</a>, as a bosshunter I'm using only this because it's most precise.<br>For example:</p><p><img alt="" src="https://www.tibiaqa.com/?qa=blob&qa_blobid=18360123636707344347" style="height:125px; width:600px"></p><p>You can see here predictions for Zarabustor, it says how many days it's on <strong>high chance and </strong>which day he was most often killed (so % chance for his spawn also)</p>also).</p><p>Akso there are bosses with more than 1 spot so guildstats is not the best option for that but you can try <a rel="nofollow" href="https://www.tibiabosses.com/">TibiaBosses</a> but it's still only high chance </p>
