Help me create Flying Pirhanas!

[Grimmy]

I need these statted up for a jungle island in my campaign setting. I want them to be pretty terrifying, and almost more like an environmental hazard then a typical combat. They would show up on random encounter tables while exploring.

I would like for them to maybe use some of the swarm rules, but take up several squares.

I'm not sure how to calculate the CR either.

Any ideas?

I would start with this.

Fish, Piranha Swarm

Then add this.

Airborne Creature template

But I am sure there are all kinds of fun templates that add flight.

And I need to figure out how to link to the pfsrd because when I tried it didn't work.

[Grimmy]

Ahh there's already a Pirhana Swarm entry? That will obviously help. Don't worry about the link I'll track it down.

Only thing I could find was from something called the City of Seven Spears.

Might work, I want them to be a real annoying menace like stirges though. bleed might not be enough.

I'm picturing the individual piranhas as small instead of tiny creatures, and the space of the swarm much bigger then ten feat. Could just use multiple swarms though I guess.

See Stirges.
Change name and appearance. Done.

Yeah, just use multiple swarms and change the bleed damage to 1 or 2 Con damage a round. 1d4 or 1d6 Con damage if you really hate your friends. >-) ;-)

I think a flying swarm is a 10 foot cube.

EDIT:

Make them UNDEAD FLYING PIRHANA and give them 1 negative level per round as bleed damage!!!!!!!

airborn pirana swarm

You could add the giant template as well and fiat it to enlarge the area as well as the size of the piranhas.

Yeah may do this (Con damage)

Undead won't fit the theme, but fiendish might?

I'd like to do something to set them apart from stirges. Maybe much faster for one thing.

Also I'm thinking swarm traits. Haven't found any rules for stirge swarms.

Thanks. I guess I could use this with the piranha swarm from FGG.

My bust... the last Stirges I used were in 4e and they were built as single and as swarms...
Sorry.
