I'm preparing to begin book five, and due to allowing a few things here and there, my players have several armies and a small fleet of airships.
The army in book four was a joke, as the players took it down rather quickly, and captured the general fairly quickly.
Here's what the players have;
They are all level 13 with appropriate and a few extras here and there due to my having to catch up due to previous GMs and the modules being stingy as well as the party tending to negotiate with most of the intelligent encounters.
A small-medium kobold sapper army, this one is mainly for maintaining defenses around the borders in the inimitable kobold style.
A small-medium kobold glider corps. Originally intended for urban and forest based skirmishes, they now come standard on a lot of the airships, and thanks to a friend of a player, now have their own flag logo.
a harge-huge Cavalier Army
a large-huge centaur army, this is mainly for defensive purposes, as in a recent battle, keeping an invading army from Brevoy occupied until the main forces could arrive.
a large-huge Magus army
a medium ranger army
a possible other large-huge army of a type I'm uncertain of at this time,
a med-large army of Ghosts, which are type of stealthy riflemen trained as snipers.
plus a small-medium airship (as in flying boats with cloudkeels) and possibly a small river navy.
Now I'm planning on Irovetti an being a very canny NPC and know that he's had an eye on both the PC's kingdom, but their adventuring party as well.
What exactly should I include to beef up the Pitaxian invasion forces just to that this won't be a total pushover on the player's part?
