Currently the new things that are added in the game are mostly locked to pure builds (Which is expected)
Reason
However there seems to be nothing specifically for hybird classes other than strength weapons (Warlords or Savant) or possibly Arcanium weapons (Conjurer or Savant possibly). This is why adding specific things for hybrid builds will make hybrid builds not just use things that pure builds were already using a long time ago but also putting more emphasis to them and adding to their identity instead of just only using 2 things at once decently
Possible ideas
Some possible ideas for hybrid spirit weapons, weapons, and techniques
A possibly a grab that resembles light magic grab attack from AA or any other magic from AA(Magic and Strength)
A sword that could have stones that store spirit energy socketed on it that a knight build could use (Vitality and Weapon)
Possibly a spirit weapon equivelent of a arcanium weapon (Vitality and Magic)
Possibly a spirit weapon that is too heavy to wield for a regular spirit user that it also need some strength to wield (Strength and Vitality
Benefits it can have
-Hybrid builds don’t always receive things last and will sometimes get things orientated to their build
-More options for savant such as going a bit for magic and specializing more for 2 stats to use a certain hybrid weapon or technique
