palundra, elemental chains are needed to enhance the attack of the opposite element. That is, you first need to take the Sense Element skill to use the chains and build an elemental altar for full use of this skill. Then, when you enter a battle, one of the elements appears on the icons of the creatures: fire, water, earth, air. For example, if you attack minotaurs, which have the fire element, with golems, which have the water element, the golem will take more damage, because in addition to the damage from the minotaurs themselves, additional damage from opposite elements will be counted. By the way, this also applies to spells. For example, if your opponent has the fire element, you can hit him with the opposite element, for example, with an ice block, and the effect will be the same, that is, additional damage from the opposite element will be counted. In short, so that it is clear and so that I don't think that I wrote all this in vain, try this skill in battle, you will immediately understand what's what.
