Hi. I'm kinda new playing games like this. Recently I took the GM role and so far my friends and I just have some basic quest sessions. I consider that the party is very well distributed so the adventures goes balanced.
I'm thinking now that the party will reach a good level, and I wanted to have a quest or session where the team must take part in a war, defending one of the wall/fort in a castle.
Is not so clear to me how or what is the best way to achieve this. I like to manage it like hordes, first a group of goblins, next a group of orcs, next some catapults and other menaces, until comes a couple of ettins or a dragon (I don't know yet).
I have some questions and I don't have much clear how I can handle. First thing, it will be a lot of enemies to control. Last weekend I tried this with a nest of kobolds (the party defeated about 20 kobolds and a big lizard). They really liked it, but for me was a bit complex, it was a moment when the turns are not very balanced (first the fighter, the wizard and the rogue, then 15 beasts and then the cleric, then another 5 monsters). How can I distribute this in a very balanced way?
Second, I try to implement some catapults. I think that the enemies can bring their own, and also the party can build their own (one is a Transmutation Wizard, and he like build things), and the rogue can sabotage it. How likely is this?
In general, I want to make a fight a large scale but I'm not sure how to have the control of this.
So far, any advice or comment you do, I'll appreciate.
Thanks.
