A new spin on the gelatinous cube: the Mirror Ooze!

Asmor

First Post
So I was browsing through Dungeonscape and got this idea... I planned on having a "hall of mirrors" where doppelgangers would attack the PCs, but I didn't quite like how cliche it was and then this popped into my head. This starts off as a gelatinous ooze with the sentry ooze and dungeon-bred templated applied, and then I added a few tweaks. My biggest concern with it is that it doesn't warrant the increased CR sentry ooze gives. It honestly seems like it should be fine as a CR 4, if not a CR 3. What do you think?

At first it appears a plain mirror, but as the glass melts away and takes form, you know that it is something else entirely. A transparent fluid-- which bears a striking physical resemblance to yourself-- steps forward leaving only the tinny backing where the mirror used to be.

Mirror Oozes were created by the dungeon lord Ixxiata as a cunning trap for would-be raiders of his dank domicile. They are trained to stay perfectly still over a mirror frame, blending in perfectly and becoming utterly imperceptible.

Here's a pretty version

-----------------------------------------------------------------

Acid (Ex) A mirror ooze's acid does not harm metal or stone.

Engulf (Ex) A mirror ooze can mow down a Medium or smaller creature as a standard action. It cannot make a slam attack during a round in which it engulfs. The mirror ooze merely has to move over the opponent. Opponents can make opportunity attacks against the ooze, but if they do so they are not entitled to a saving throw. Those who do not attempt attacks of opportunity must succeed on a DC 13 Reflex save or be engulfed; on a success, they are pushed back or aside (opponent’s choice) as the ooze moves forward. Engulfed creatures are subject to the ooze’s paralysis and acid, and are considered to be grappled and trapped within its body. The save DC is Strength-based and includes a +5 racial bonus.

Paralysis (Ex) A mirror ooze secretes an anesthetizing slime. A target hit by an ooze’s melee or engulf attack must succeed on a DC 20 Fortitude save or be paralyzed for 3d6 rounds. The ooze can automatically engulf a paralyzed opponent. The save DC is Constitution-based.

Sticky Fingers (Ex) A mirror ooze which hits an opponent with its slam attack may move into the opponent's square and attempt to engulf them as an immediate action.

Transparent (Ex) Mirror oozes are hard to see, even under ideal conditions, and it takes a DC 15 Spot check to notice one. Creatures who fail to notice an ooze and walk into it are automatically engulfed. In addition, the transparency grants the ooze the benefits of concealment (20% miss chance).

"Sticky Fingers (Ex) A mirror ooze which hits an opponent with its slam attack may move into the opponent's square and attempt to engulf them as a standard action."

Given that the Mirror Ooze only has one attack a round, they could never use this special ability.... did you mean 'immediate action'? More like:

Sticky Fingers (Ex) A mirror ooze which hits an opponent with its slam attack may move into the opponent's square and attempt to engulf them as an immediate action. This movement uses the Ooze's 5' step for the round and cannot be taken if the Ooze has already moved.

Reducing the CR makes since as you are also reducing the size from Huge down to Medium.

Now, if its a Hall of Mirrors and the Ooze splits to hide on multiple mirrors.. then combines itself back into the full size :)

{or at least into Large using 3 mirrors...get the Reach ability back }
 

Woops, I actually meant to put Sticky Fingers as a free action. >_< Immediate action probably works better, though.

Unless I'm missing something from the Sentry Ooze template, the base creature before dungeon-bred would be large, and then dungeon-bred reduces it to small. It was never huge.
 

The original gelatinous cube is huge. I didn't know the templates reduced the size... tend to play pure 'Core 3' when it comes to monsters.

but you have this one as medium.. not sure how much that kills the CR, altho the loss of reach is a definate impact.
 




I threw it at the party today. Decided to call it CR 3.

3 oozes vs. 2 level 5s and a level 6.

Total slaughter. The oozes couldn't hit, the reflex saves were very easy if they tried to engulf. It wasn't a battle at all, the players just mopped them up. I think I might have done 2 damage and made them use 1 action point.

I'd call them CR 1 at best after some playtesting.
 


Perhaps if the oozes gained a touch attack instead of a slam? Something that paralyzed to give them time to engulf.

Or for more fun, the oozes don't eat flesh; they engulf and eat metal. Say goodbye to your ill gotten gains, adventurers! Mwah ha ha!
