As of version 3.0, we have no reliable information regarding the weapon or type of weapon that will be used by the Dendro Archon. However, the speculation is that she might be a catalyst user; this will be a good change because we already have two Archons that use a polearm and one Archon that uses a bow. Additionally, if she is a catalyst user, then the game will have a five-star Dendro catalyst character, which would be well suited to be a Support character. She could potentially aid the players in carrying out a vast majority of Dendro reactions which would be great because of the new Dendro-Electro META that seems to be highly effective.
