Units should get an attack bonus if they attack something that is below them, and get an attack reduction if they attack something that is above them. For details, see:

Attacking is implemented in Game::SimulateMeleeAttack() in src/FreeAge/server/game.cpp.
It might be useful to add a function to ServerMap to interpolate the elevation at an exact location where a unit stands on, using bilinear interpolation. It might also be useful to define a threshold for a minimum elevation difference for the attack bonus/malus to kick in, otherwise the results for units at a similar height might appear somewhat random.
