We do not know what the 4th companion is, we do not know what the “class-specific mechanic” is and only one passive (Call of the Wild) seems to work well with all of the companions. Assuming the 4th companion is a damage dealing beast and the “class-specific mechanic” works well with any build. How will you run your druid?
Options:
- Mostly Earth Magic.
- Mostly Shapeshifting.
- Mostly Summoning (companions).
- A mix and match of the above.
I will go with Earth Magic and Companions.
