Clerical Weaponry Option

My group has long used the "Clerics use the weapon that their god uses" houserule, rather than the "guess I'm using a mace" rule.  I'm considering implementing a system in which this specific weapon gains increased bonuses and other powers as the Cleric advances; for example, a bonus of +1 when 3rd lvl is reached, +2 at 7th, +3 at 12th...  Special Effects will be included as well; the weapon of a devotee of a "Fire god" might become a flaming sword, or have the power equivalent to a Burning Hands spell twice/day, maybe even a Flamestrike option at higher lvl, while the trident of a sea god's Cleric could grant Water Breathing, Create/Purify Water, etc.  A special ritual must be performed by the head of the Cleric's order once the appropriate lvl is reached, or perhaps a quest must be performed... the specifics differing depending on the god being worshiped.  Only the Cleric can access these powers; for anyone else, the weapon is not magical.  Of course, the Cleric must be mindful to use these powers only in the service of the god, else the power will be revoked or suspended.  I like the idea of the Player knowing he's gonna get something cool - provided he earns it!  "Can't wait until I'm 12th lvl, and I can Disrupt Undead with my spear!"

Signs of the Times

"Hobo Symbols of the Great Depression" = Adventurer Symbols of the Megadungeon?

Could be used by the PCs, Thieves Guild, or a secret cult, or found by them while duneoneering, used as hints, misdirection, red herring... 
Several would require a broad interpretation, or even an alternate meaning to incorporate into a fantasy setting.  Could also be adapted as a Random Encounter or Random Dungeon/Town  Design table, or your next Dungeon/Map could be marked with symbols...
Several more charts of varying sizes can be found with an image search.

"Mul-ti-pass"

Monster Monday 3,

This is possibly the most Lovecraftian thing I ever hope to see...
and I don't even dare to imagine it's
weird appetites and disturbingly Freudian motivations...

...but if anyone is sick enough to stat it up for me,
all I can promise is I'll use it in my game and let you know how it went

The "Thank You for Coming" Potion

Whenever a new Party or Character is created, the PC(s) automatically receive a "Thank You for Coming" (random) Potion, assumed to be part of their starting/current equipment.  Gives 1st Level PCs a little boost, makes new/"replacement" PCs feel welcome, and also makes them a bit less jealous of existing members and their preexisting loot!
