Never leave an old man his "walking stick", NEVER!
Why stick to the same old staves of yesterday, when you can pick up the latest in adventuring tools? #30 Staves1 provides a wide array of options, from the awe-inspiring staff of the planetripper to the mysterious staff of portents to the fearsome staff of the fleshwarper. These staves permit characters to summon a black pudding (like the staff of the dungeon's warden), or control the light and darkness with the legendary shadowstaff. This book also contains rules for greater and lesser staves.
So why stick with that plain old staff your character has been claiming is just a "walking stick" for the last ten years when you can get something more? Get #30 Staves!
I see that the gentleman who wrote "#30 Haunts for Objects" did this one too. It ought to be pretty good then, given the job he did on that one. If anyone got it yet, can we get a word on just what the listed staves are like? For instance, do any look like they'd be especially good with a staff magus?
