You won’t believe what you can do with a freshly captured soul! Let me tell you something about it!
First of all, you may ask how to capture a soul. Capturing souls enables you to deal with monsters you’ve already defeated. You can fight these monsters after summoning them to a specific place. You may also learn the spell "Soul Capture" in the Bulb Cave on Pandala Island. This spell will help you capture souls of a group of defeated monsters inside a soul stone. You can buy such stones in the bigger cities of DOFUS.
To capture a soul, you must have a soul stone with a higher level than the most powerful monster of the group you're going to fight, and equip the stone to replace your weapon. When in the battle, you should fight against the leader of the monsters with the spelling. This spell has a limited time of effectiveness! The souls of a group of monsters can only be captured once. If there are many players involved in the fight and they’re all want to capture the souls of monsters, each of players will have a chance.
However, the players with the highest prospecting will be the first ones to try and will have a higher chance to capture the souls. There are many different types of soul stones with different quality rates. The higher the quality of the soul stone, the higher the chance it will work.
May be you not succeed in capturing the soul; the soul stone won't be destroyed. You’ll be able to reuse it next time!
