something weird in the Manual of the plane

[abri]

For a while there were a lot of discusion on the ECL of various monster, lots of different opinions too.
Just reading my manual of the plane yesterday and looked at the Equivalent level of the creature there... Well I guess we missed two of the most ridiculous ECL one could find:
Uridezu ECL+5
Canoloth ECL +4
Couldn't believe it when I saw it: for info, they are CR6 and 5, with 7 and 5HD, and about a page long of abilities, including DR, poison immunities, telepathy...

Problem is that I already promised my players that they could play an Uridezu if they wanted, and one was interested. Now can someone give me a rough estimate of the REAL ECL of this demon? Before the player's character dies and he makes a new one .
BTW, for demon character, are the players supposed to keep the summoning abilities or not? Seems interesting for Role-playing (with the "paying the favor back") and a great tool for the DM to latter introduce plots, but it seems overpowered.

Note: Yes I am the kind of DM who alow their player to play weird stuff as long as they have pages of background written and that they are not optimal combo.

Yep. If you don't let them have it, you need to lower their ECL. In theory, all of a monster's abilities are factored into their ECL.

I have no doubt that the Canoloth entry is an error. In the 12st chart it is listed as +5, and on the XP chart it is given as +4. Under the new rules, the minimum it could be is +5. More likely it should be +10!

This creature is totally unsuited for PCs, of course. It can't even make a good NPC. How are you going to play a blind bulldog bred and trained only to kill on command?
