Modifying monsters how do these look?

[Jgosse]

I am making some custom monsters for a 2-3 session campaign that I am running and just wanted another opinion on how they look.
the party will be 4-6 players of 5th level chosen from pre generated characters I made on some website fastcharacter.com or something.


Armor Class 16
Hit Points 25 5D6+10
STR 12 DEX 16 CON 14 INT8 WIS 12 CHA 6
Saves Reflex 5 Con 4 Wisdom 3
Skills Perception 3 Stealth 5
Multi Atk
2 Claws +5 to hit 1D4+3 Slashing
Bite +3 1D6+1 piercing

Supposed to be easy 4-8 depending on party size.

Armor Class 18
Hit points 65 10D6+30
STR 14 DEX 18 CON 16 INT 10 WIS 14 CHA 6
SAVES STR 5 DEX 7 WIL 5
Multi Atack
Attacks
Four Claws +7 to hit 1D6+4
Two Bites +5 to hit 1D6 +2

supposed to be a bit of a challenge but nothing to dangerous.
Guard drake
Large Dragon
Armour Class 18
Hit Points 150 20D8+60
Speed 40
STR 18 DEX 14 CON 18 INT 4 WIS 10 CHA 8
Skills Perception 4
Damage resistance Fire /Lightning
Darkvision 90Feet
Passive Perception 14
Multi ATK: The Drake can Atk 4 times Bite, two claws, and tail.
Bite +8 to hit Reach 10 Foot Reach 1D10+6 piercing
ClawsX2 +8 to hit 5 foot reach 1D8+4 Slashing
Tail +8 to hit 10 foot reach 1D8+4 Bludgeoning

Roar 15 foot cone 5D4 damage
DC 18 Con Save for half. On failed save deafened for 1d4+2 rounds

hoping this will be a tough fight for the party.

Your math is wrong on the Guard Drake: 60/20 (Effective Character Level, AkA 20d8)=3. For a 18 Con, this number should be a 4.

The rest appears to be correct. Just had this in front of me, and had the urge to point it out. This way it's just random numbers that make up the Guard Drake's hit points. :P

Looks like CR 7 to me. A party of 4 level 5s would be bit less than a Hard encounter. It wouldn't be a Medium encounter for a part of six.

I'd add one regular guard drakes for a party of five or six.

Thanks for catching that for me.

Cool thanks for the input.
