[Titus Marcellus Scato]

The bigger the ship, the better it performs in battle against smaller ships.

Think of it in terms of WW2 warships, but taking into account only gun firepower, and assume that torpedoes and mines have not been invented. (And, of course, there are no submarines, and no aircraft carriers.)

With that in mind - the bireme is like a destroyer. The trireme is like a cruiser. The quadrireme and quinquireme are medium and large battleships. And a gigantic Nees Megistai (Huge Polireme) is like the super-battleship Yamato, but even bigger!

Now - if destroyers didn't have any torpedoes, but only their little guns, one battleship could easily fight off a whole squadron of destroyers by itself without taking much damage in return. And it takes a lot of cruisers to put down a battleship. and losses will be heavy.

Hope that gives you a rough idea of what to expect when pitting one type of ship against another.
