Before the Germans came and settled in this region there were only a few Cedar trees that grew slow and very big and one trunk. I know these trees and can over look them. They were here long before the white settlers.
The ones I speak of give very little food and shelter to any animals. The trunk of the tree is not one but many. They were planted and used by the settlers of this region to use as fence posts. The posts today are made of mettle. They suck up the water and choke out other trees of this region, the live oak, the mesquite, and ash to name a few. The only canoe that can me made from this unwanted pest is perhaps one for Barbie and Ken to go with their summer home and spring time jeep.
They rank right up there next to our hog problem here. Now where is my box of kleenex?
I still can't believe with the clues I have given you no one has guessed what these creatures are yet. They are out of the 2nd Edition AD&D and the full D&D Monster Encyclopedia they are not a DM creation.
Once you figure it out or I reveal then you'll be like oh no s**t duh
I need to read this QA more often. Also used my Non-Weapon Proficiencies of Ancient History (+5) to know the enemy and such posting as such. If this does not sit well with you Tan let me know and I will edit.
Most DMs I have played for require you to put a magic hold on them or hold their hands from making the movement. If a magic user does get off the spell then you are along for the ride.
Plane shift would be harder to physically hold them in place because most critters that can travel that way do it at will. This would call for them to be knocked out or dead. Most DMs (again as above) would say no you do not go with them when they plane shift.
But you have those GMs that make the call a little differently.
My apologies but I have been sick the last three days since I started feeling crappy Thursday afternoon. Then we lost power Fri morn and things from that point just got worse with a visit to the hospital. I will try to get a post up tonight but make no promises.
