Black arrows spawned by the Darkwing Fall node in Aerial Assault cannot be picked up and can sometimes fall outside of navigable terrain/inside walls, especially in indoor/cave tilesets.
Currently with the 2 minimum points in feather storm duration to reach the black arrows, feather storm spawns 9 black arrows over its duration (which should be 7 tbh going by the 5s with 40% increased duration), but the arrows fall in strange places or off-screen unlike the black arrows from the base skill.
Near terrain often only 1-3 arrows are visible as the rest fell outside the map. And then, well. They canât be picked up anyways so the node is currently dead.
