Bonds

[Grimmrok]

It's just something about your hirelings growing bonds with eachother the more they interact with eachother, fight alongside eachother, work beside eachother, etc.

Said actions would increase the bond between your faction's members, and this could give small bonuses to characters with strong bonds when being near eachother.

It would be a nice touch to the game, IMO.

It could be nice. A bonus in the very same thing they grew doing together.
- People working in the same machine (or chain, like "I do the chainmail, then you do the chainmail sheets", or "I give you the strawflour, you do the bread, this other is doing the foodcubes with your bread"), bonus in their kind of task while they do it together.
- People exploting the same field, bonus in labouring while they do it together.
- People travelling together, bonus in some fighting stat, depending on their speciality (like medic if one is a medic, robotics, etc, or maybe the highest and the lowest of the fighting skills at the same time - let's say defence and toughness, or attack and defence, you get it) while they travel together.

It could be not stackable, or minorly stackable as the "friend" group is bigger (for example +5 maximum).
