@RickAJr As a new DM, I truly appreciate these posts. If you have the time, I would appreciate reading these on all of the monsters that one may encounter while playing through the Lost Mines of Phandelver. Thank you!

The 4th edition books often have lore for different DC rolls. I find those useful for giving players some info when they take the trouble to investigate before wading in with combat.

I appreciated this thinking and will incorporate this the next time I run it :)

This is the best advice I have received around Skill Checks.

Thank you.

these things are so annoying and anyone who fights it should use non-slashing attacks unless they want to die.

I get that the new jellies are smaller and have less hitpoints, but shouldn't they also deal less damage ?...

Pseudopod. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 9 (2d6 + 2) bludgeoning damage plus 3 (1d6) acid damage.

Can someone explain to me what  Hit: 9 (2d6 + 2) means?

@Nmiller88 It's the damage after an attack. The 9 is the average damage it will do, and the (2d6 + 2) is the formula for the damage if you want to roll for it.

Very nasty and deadly towards low level characters. I actually let the ooze spend the action round splitting into two ooze (subject of succesful slashing attack ) and attack next round instead. Admit it was just a temporarily respite for the player characters but they got the idea of the slash dmg not being very effective. 

Just found this, so awesome.  Thanks!

So how many times can it split? One large to two mediums. Two medium to four small. Is that it? Or could it potentially keep splitting? Just curious. 

Edit - I just reread it and after small, it seems it cannot be split anymore. ;-)

How to beat: get a paint brush and beat the devil out of it    

That description gives you two options when dealing damage.  You can save time from rolling damage, and just deal the 9 damage, which is the average, or you can roll 2 six sided die, and whatever you roll add 2 to it for the damage (2d6+2)

 Is the Jelly actually a Large creature? In Dwarven Excavations, an Jelly resides in a tunnel only one tile wide.

It has "Amorphous. The jelly can move through a space as narrow as 1 inch wide without squeezing."

So, for clarification, it has resistance to all slashing damage magical or ot, correct?

is it just me, or does this look weird?

Yes

I'm imagining an "Orange Dragon." It's a winged Tarrasque that horks up Ochre Jellies for a breath weapon.
