It is possible to follow the Boltreaver Astalos in Azuria prior to you ever leaving the first territory. To begin with, you have to acquire a standard Astalos.

This monster is not common but only appears once you have defeated a certain invasive monster in your map. The way to get there is to find a wind funnel on the lake and glide over.

How to Trigger the Mutation

Having an Astalos, you have to abide by three rules in order to acquire the new form. In Monster Hunter Stories 3: Twisted Reflection, the place where you store him has to be a habitat of thunder elements.

Another thing that you should do is to train your Astalos until it attains S-Rank in that location. And lastly, you must have the three thunder monsters inhabiting that place with you. As Astalos is a thunder type, he is the first one of the group.

The Best Way to Finish

The easiest method of doing so would be in the Broadleaf Basin since it already has Tobi-Kadachi there. Lagiacrus is the second thunder monster; Lagiacrus can be won after you defeat an enemy of invasions in one of the caves in Azuria.

Having Astalos as the third monster, you need only to reach the S-Rank in order to get the Boltreaver Astalos.

Attack Skills and Genes

This is such a monster with the right moves to make. Rayblade is one-hit powerful and consumes a substantial amount of stamina, and has the capability of paralyzing your opponent. Blue Plasma is highly comparable, except that it strikes everybody on the other side at the same time in Monster Hunter Stories 3: Twisted Reflection.

These two are technical attacks. There is also the Azure Voltage, which enhances his thunder power by a huge margin but reduces his defense. It also provides a power charge, which makes his subsequent hit powerful.

His special swing is referred to as Astalos Saber. It is a single-target attack and extremely probable to score a critical hit. It is quite a solid method to inflict a lot of damage at the right time.
