Campaign Mastery

How do you handle PCs who seem to be immune to magic?

A recent inquiry in Ask The GMs asked us,
Hi! I’ve just started an AD&D campaign where the all the PCs have got really good saving throws. Less than 50% of any spells I cast on them will work on the Dwarfs and Halfling Priests [...]

There came a time when I had to move out of the city (where my players were), and back to the small town in which I had grown up, for financial reasons.
That would spell the end of most campaigns, but I had willing players and exceptional determination. I would write a scenario each week while [...]

How do you extrapolate from existing rules to cover new situations?

Recently, Campaign Mastery was asked,
If a giant has rapid shot can he throw 2 rocks in a full round action? (d&d 3.5)
This sparked some debate over whether Campaign Mastery should answer rules questions of this sort; we aim to deal with big-picture and comprehensive situations [...]

Traps in some game systems are standalone elements. However, I consider them a hazard if they factor into a combat in any way. Encounters without combat that just have traps in them I would consider hazardous for your health, but not a combat hazard.
Traps have been around RPGs since day one. In my first D&D [...]

The first type of hazard we talked about was Terrain. Another variety of combat hazard is environmental. What are the physical surroundings like? Are there any interesting global effects in place?
My definition of environmental hazard is one that affects everyone. If a hazard is limited to just certain areas of the battlemap, then it is [...]

A classic combat hazard that hearkens [...]

The first helping hand you can offer your poor, underrated and under-appreciated combat hazards is to give them a great name. A name with gusto, panache, or spirit gives hazards a surge of vitality and interest. A great name inspires.
Instead of calling the mud in the middle “difficult terrain”, call it Grom’s Brown Demise. Rename [...]

Throw hazards into your combats to make fights more interesting, regardless of game systm or genre. Dungeons and Dragons, for example, has always promoted dungeon masters using traps and difficult terrain, though in the latest edition there seems to be more urgency for doing this.
To start this series off, I’d like to provide a working [...]

How much, if at all, should the final villain of a long running campaign pull his punches?

My campaign boss [villain] is a high level wizard with access to epic spells, and my party just made 20th level. They are on the way to fight him. Should I open up with his most powerful abilities, or [...]

Nobis is a game supplement about to be released by Pantheon Press for the d20/ D&D 3.x game system. Campaign Mastery was priviliged to be amongst a selected number of blog sites given a pre-release glimpse of the new release for review. Although this commentary will focus on the Background to the city-state that is [...]
