Last night at Encounters at my shop we fought an Ochre Jelly. The Ochre jelly split in two.
One of the characters played a card afterwards on his turn that said "all bloodied creatures gain 5 temp HP's"
The DM tried to give the HP's to the Ochre Jelly reasoning that it was still the original Ochre jelly and still officially "bloodied"
The players argued this point and the DM said fine we will treat them as two, brand new seperate creatures.
Now the fun part, before the Ochre Jelly split one of the party memebers was playing an Avenger (yes I know not an Essentials char yada yada) and he had used his oath of Enmity power on the Ochre Jelly.
After the Ochre Jellies had perished (the split ones) he tried using his oath of Enmity again and the DM said NO ruling that since the Ochre Jelly had split into two seperate Ochre Jellies the ORIGINAL Ochre Jelly had never reached 0 HP's therefore not triggering Oath of Enmity being available again.
My thoughts are as follows:
1) It says the Ochre Jelly splits into two creatures, all effects fall off, and it's remaining hit points are split between the 2 - basically saying that it's still the ORIGINAL Ochre Jelly. Technically it is no longer bloodied as it's remaining HP's are divided between them. No HP's for the Ochre Jelly.
2) By this logic the Ochre Jelly is still the Ochre Jelly albeit in two parts. When both die, it is reduced to 0 HP's thus triggering the Oath of Enmity.
The DM's logic was it was either the Jelly gain the Temp Hp's and Oath Triggers, or the Jelly doesn't gain the HP's and the oath does not trigger.
I believe both these options are incorrect.
