Some unique tech ideas

1. Frank tech-more cavalry armor. Since bloodlines Frankish knights are not as unique as they were in AoK but this will make them unique again. Can replace the stable's work faster tech with this.
2. Persian tech-War elephants deal area damage upon death 100% to enemy and 40% to ally. Just something to spice things up.
3. Teutons tech-Teutonic knights gain bonus stat(idk can be armor/hp/speed whichever is most balanced) when grouped. 1% bonus for every 5 knights. Or Teutonic knights gain self healing when grouped. Example : 5 knights together regen 1hp/s but 10 knights give regen 1.5hp/s, then 20 knights 2hp/s and then finally maxed at 3 hp/s for 40 knights. Yes every knight will regen that amount if you were confused. I don't think it will be op because teutonic knights have been a meme for a long ass time And this help them not get totally destroyed by onagers but won't make them op either as they will lose their healing when you pick off the weakened ones with your archers also they will be still slowest unit in gaming so can't just run over to your mangonels and shit.
4. Saracens tech- Archer and cavalry archers move faster. Saracens rely on their archers mostly as mamelukes are expensive af and they should be able to research something to help with that, especially considering tbe funny civ bonus.

Historical relevance : 1. Frankish knights were notorious for their armor. So remove husbandry from the tech tree if needed but still give them this tech. 2. People could fall under the elephant and also shit themselves hearing the cries. 3. Teutons were hospitallers so they could make hospitals and heal their soldiers. 4. Saracens were good archers. They would shoot arrows all day and run around while the crusaders were walking after them.
