New Unique Unit idea- Hero Shrew Archers?

I saw a recent reddit post pointing out the miraculous strength of the Hero Shrew and couldn’t help but think how much sense it would make as a UU for an aoe civ. Just so I can say I r/SavedYouAClick, the post showed that Hero Shrew can sustain about 160 pounds on their backs due to the unusual nature of their vertebrate. An expedition team had a man literally stand on one leg on the Hero’s back, and when he got off it walked away fine. When I found out this little sampson shrew hailed from the jungles of the Congo, I knew I had to introduce it as a new civ UU idea.

The Hero Shrew Archer (Calvary Archer)

Unique Unit to the Kongos (Kingdom of Kongo civ) seeing that it lives and burrows in this area.

I pretty much think an archer would be best to mount this unit since they are small and weak and have no armor and most of them would be under 160 pounds- the archers that is. It would get Calvary Armor upgrades and Archery Attack upgrades. Thumb Ring and Ballistics apply, and it gets husbandry/bloodlines.

The game changer will be that this unit can burrow under woodforests and reappear in cut areas, albeit at a 1 second delay for each tile it has to go through. This makes sense because the Hero Shrew is special in its ability to tunnel, burrow, and man-handle its way under the Congo forests where it currently reigns.

Cost: 30 wood 45 gold

Trained at Archery Range

Speed: About as fast as Eagles for balance

HP: 80

Attack 4 pierce (To balance)

Attack bonus +3 against villagers since it will be used mostly as surprise wood raiding unit.

Fire rate: 2.5

Range: 3 (For balance on surprise woodline raid)

Melee Armor: 1 (Because it isnt hurt by briars)

Pierce Armor: 0

Elite HS Archer upgrade: 300 food, 900 gold

Gives +2 Attack, +2 Range, +10 HP, and makes creation speed close to Karambits but not as fast. Also speeds up tile tunnel unique ability to .75 seconds per tile. Obviously this is a bit OP, so the Elite HS Archers will have to rest every 1 minute so they can handle the extra weight of Elite Archers armor on their backs.

The Hero Shrew will be weak to mangonels and castle fire because they’ve never encountered Stone Castles in forests of Congo. They are immune to Monks because the local legends mystify the shrew, and its otherworldy strength pretty much confirms that. So the best way to use Hero Shrew Archers would be to send them to enemies woodline (Under forests, if you can handle the tile-tunnel delay) and have pocket spam eagles into front of base. Eagles immune to monks and kill horses, Hero Shrew Archers pop up in back woodline and gut villagers (Monks cant help here either).

Best way for enemies of HS Archer to defend is build castle in back of base or keep a mangonel near woodlines. It would be inherently weak on maps with low wood like Arabia, but you may find use for them in Blackforest (Just mass 70 of them and send to every woodline for small momentum shift)

Of course there isnt a current civ that could take this UU, but if we get another Africa Empires DLC they should atleast consider it seeing that it is so central to the Congo culture and is a great symbol of their strength.

Please comment ideas or feedback to make the unit best for the aoc!
