A full potion of this draught must be drunk in order to make its effects be felt. 

It will influence 1 or 2 giants as if a charm monster spell were affecting them. 

If only 1 giant is so influenced, it is entitled to a saving throw versus magic at -4 on the die roll; if 2 are influenced, the die rolls are at +2. 

Control lasts for only 5-30 (5d6) rounds.

The type of giant subject to a particular potion is randomly determined as follows:

1-5 hill giant

6-9 stone giant

10-13 frost giant

14-17 fire giant

18-19 cloud giant

20 storm giant
