Situation: You felt like pranking someone on the Server how would you do it. Remember, no griefing.
What I would do is start putting Jelly cats all over Scars village and keep on doing that until he starts getting irritated.
I'd leave a piece of diorite at the base of the Omegatree.The next day,I'd leave 2,then 4,then 16,and so forth until Iskall notices and removes it.
The next day,I'd place the required amount of diorite INSIDE the Omegatree..
Move all the signs on someone's storage system around, then disorganize their chests.
Fill a bace with water
When Iskalls logs off, I would surround him with diorite. arrond the diorite, there would be obsidian. this is for the floor and every thing else
Give them a 'present' with an observer wired into a battalion of TNT in one of their builds, but the TNT were surrounded by obsidian and water and they have an heart attack.
What do you think?
