Motes are little creatures which aid you in the battledome, helping out of all sticky situations with their close attacks some defend whilst others attack, and maybe even some do both!
Ash Mote: kicks up ash to make cloud
The Ash Mote stops you from getting hurt and also has a dark attack. It also defends your pet. (found in the lost desert as scorched sand)
Bubble Mote: creates a bubble round your pet
The Bubble Mote is the best fire defence mote, preventing you from both dark and fire damage it can also protect you from physical attacks by turning you invisible.
(found in the remains of maraqua)
