How to filter buffed entities based on scene id in client side?

        Buff buff = entity.get(Buff.class);
        switch (buff.getType()) {
            case BuffTypes.BODY:
                EntityId sceneId = buff.getTarget();
                getBuffSet(sceneId).add(entity.getId());
                sceneIndex.put(entity.getId(), sceneId);
                addToCommit(sceneId);
                break;
            case BuffTypes.MOBILITY:
            case BuffTypes.ACTION:
                EntityId bodyId = buff.getTarget();
                sceneId = buffSet.getEntity(bodyId).get(Buff.class).getTarget();
                getBuffSet(sceneId).add(entity.getId());
                sceneIndex.put(entity.getId(), sceneId);
                addToCommit(sceneId);
                break;
        }

See… from an ES design perspective, this is the kind of thing that totally baffles me. What do these totally different aspects have to do with one another. Why is “BODY” a buff type and “ACTION” a buff type. It feels like something is missing in the design when these two basically unrelated things find themselves siblings in some switch/case block.
