Part 2 of my Persia project- Myth units and human units!

Falchion warriors as infantry- Good against cavalry. Trainable at a military building(undecided on name) in the classical age. Composite archers as archers. Good against infantry. Trainable in classical. Dromedary fighters (camel riders)- Cavalry. Good against archers. Classical age. Horse driven cart archers- Counter archers. Trainable at the heroic age in a counter barracks. Counter infantry- Kopish swordsmen. Heroic. Dromedary dismounters- Camel riders who dismount when they see travel ahead and use camels for travel only. Counter cavalry. Sparabara- Trainable at the palace in mythic. Have a 2 metre spear and a shield which they use to block fatal attacks on weaker soldiers as their special attack. Herodotus' immortals- Trainable at the palace in mythic. Change weapons depending on who they're attacking. Change to a spear for cavalry, a sword for archers and a bow for infantry. War elephants are also trainable at the palace in the mythic age. I need more siege weapon ideas! Help!

Myth units! Mithra- Shabrang. A night coloured horse that can turn invisible when it is vulnerable and escape. Verethragna- Simurgh+ Bahamut. The Simurgh is a benevolent bird that fires firebolts at enemies from afar. The Bahamat is a sea creature which cannot be damage and intermittently sinks enemy ships from below the ocean's depths. Hvar Kasta- Peri. Mischievous winged spirits that can heal allied units and infatuate enemy units to bring them to your side. Ardvi Sura Anahita- Karkadan . A mythical creature which is enraged by enemy myth units and animals. Has a special attack when faced with enemy myth units where it spins round in a frenzy, damaging all nearby units. Atar- Azhdaha. A dragon-like creature that can be spawned at the dock as a sea creature, and at the temple. At the temple it can be spawned as a land creature or a flying creature. Breathes fire on enemy units and whips its tail forwards to sink enemy ships or kill enemy soldiers. Rashnu- Shahrokh. The legendary king of the birds who can fly down, grab enemy units and hurl them into oblivion. Flies down to battle and scratches enemy units. Vayu- Fulad-Zereh. A huge Horne's demon that headbutts enemies and blows them away. Zorvan- Hadhayosh. A fearsome primeval ox that can freeze enemies in time and maul them. I need ideas for upgrades for each minor God(you know how each minor God gets 3 upgrades). Read my previous post for what the Gods are of and stuff and then make some suggestions! Thanks!
