Minion Craze or Portal Pleasure

This encounter remains to be one of my groups most favourite and is still talked about to this day.

The room has no monsters except for minions, the general goal is to disable all the portals, and activate another one so the party can leave

Each blue square is a portal. And are far enough a part it’s hard for the wizards to make it to one each turn

At the start of combat and on each minion’s initiative, every active portal summons in a new minion who goes immediately.

To disable a portal requires someone to be adjacent to it, standard action, arcane {Trained} check DC [(5 per tier) + 15]

The pit in the room should be at least 10 feet per tier, and is used by the minions.

This encounter can go on for a few good rounds since the players need to climb back up and in, and it can get out of hand fast since 12 minions per round are going to be spawning in. But it is loads of fun for everyone

I used a Modified Groom Guardian, only difference was it had Fly (hover). I recommend the same but adjusting it for whatever level you need.

**Rules note: I’m not sure about the rules of teleporting something in air, but it is one of those things that as a DM you should allow in the case of the monster because it is indeed an attack**
