<p>When you use your rein it can happen one of the following:</p><ol><li>Tame the monster</li><li>The monster run away</li><li>The rein break</li></ol><p>There is no official statistics about the percentage of each. The percentage may change from item to item but for the itens items that have a chance of breaking I guess its 50% of running away, 30% of taming and 20% of breaking the item from my experience.</p><p>You can also check <a rel="nofollow" href="https://www.tibiaqa.com/3723/what-taming-items-dont-ever-break">Taming itens items that won't break when using</a>.</p>
