What about a skeletal race(backstory time!) the skeletons are the ones summoned by necromancers but some of them found out that they were only minions and were formerly human so they decided to leave and make a clan of their own! The skeletal orcs can join their clan too
Worker-skeletal worker - looks like skeletal warrior but holding a hammer instead
melee units-skeletal warrior-basic melee unit,capable of reboning (works like cannibalization but faster),skeletal orc grunt-stronger than skeletal warrior
Skeletal giant-2nd strongest melee unit has Reinforced bones upgrade,Skeletal orc champion-1st strongest melee unit
Ranged-skeletal archer-basic ranged unit,burning archer-advanced ranged unit and it has immolation
Siege units-Bone titan-looks like a giant skeleton with armor moderate speed
Bone Cannon looks like a cannon but it shoots skeletons
Flying units Skeletal drake-looks like frost wrym but has no scales only bones
Ultra unit-Fallen champion-looks like an undead general,can cast dutys call which ressurects allies from the dead
