Subclass Synergies

If you take a broad look across all of the different class options, they mostly make sense as to which force they draw power from, and what category they fall under. The subclasses however, both add even more differences or even overlap in mechanics and lore. The Planes caller and Shaman class, even though they have no subclasses, may have options that fit in with one of these categories.

This list groups up subclasses that are similarly themed, draw power from a similar place, or share a common mechanic concept. While this list is by no means a requirement or an extra place to minMax, players looking to have ties to other party members, or work with similar mechanics can certainly find the correlations here.

A particularly generous or inspired DM might give rewards or opportunities to players who have synergy, as it makes writing a plot for the campaign much easier when characters are tied to one another whether it be through source or organization. This is not a hard rule however, so don't let the "potential" for rewards steer your decision. It is meant as a guide flavor and lore wise, which can lead to linked mechanics.
