This guide contains the following information.

This tool finds the total support bonuses between two units at all support levels, and calculates how many turns it would take to get to each level.

The support points between units is maintained internally by the game. Once two units reach a certain threshold of point, they will unlock a support conversation by using the "Support" command when adjacent to each other. No additional support points can be gained until the conversation has been viewed. It takes 80 points to get each support level. The following table lists the point thresholds.

To build support between two units, simply place them adjacent to each other by the end of the turn. Each unit pair (that can support with each other) has a hidden value for how many support points they will gain for each turn that they end next to each other. To go along with this, each pair of units also has a base support point value, which is how many points they have the moment both units are on your team.

For example, Eliwood and Hector have 72 base points, with a gain of 3 points per turn. Hence, Eliwood and Hector have to end three turns next to each other to gain the C support. The slowest building supports have a base value of 0 and a gain of 1 per turn, requiring 80 adjacent turns to even reach a C support. An example of this is Matthew and Jaffar.

Each unit can have up to 5 support conversations. Unlike FE6, there is no hard support point gain limit per chapter. However, each unit can only have one support conversation per chapter. This means that units can only gain points right up until the threshold of next level after having a conversation. For example, if you have Renault and Bartre wait next to each other for 80 turns in Victory or Death, they will unlock their C support conversation. If you wait another 100 turns, they can only gain a further 79 points for a total of 159 gained in that chapter, because gaining more would result in a B support conversation. Then in Light (Part 1), they will unlock their B support after ending one turn adjacent to each other.

The bonuses given to each unit pair depends on their affinities and support level. Each affinity has set bonuses for each support level. Units with support between them will gain the bonuses for both affinities, for example if Rebecca (Fire) and Louise (Light) have attained a C support and are within 3 tiles of each other, they will each gain 1 Atk, 0.5 Def, 5 Hit, 2.5 Avo, 5 Crit, 0 Crit Avo during combat. Any bonus decimals are rounded down. The following table lists the bonuses at each level for all affinities.
