Ptolomaioi having Elephant Cataphracts?

[Krusader]

Also with factions who historically used them but had no territory where elephants existed i.e. Seleucids and Epirotes, the game tries to represent the fact that their armies could and did include Elephants.

Therefore the Seleucids can recruit Indian Elephants in Antioch to represent the fact that they would have traded with whoever owned India in order to obtain several of these beasts. Same goes for Epirotes.

I do have one question. How were Phyrrus' elephants transported to Greece and then to Italy? Were special transport ships needed to ferry these beasts?

Plutarch wrote flat-bottomed transports. If you have access to JSTOR, see if you can find an article on Ptolemy Philadelphus' Elephant Hunting, which has a description on the ship the Ptolemaioi designed.
