Effect
Makes 4 Great Fireball Runes (requiring 1 Blank Rune). 
Shoots a large circular flame attack based on the center of the selected area, this is the Sorcerers' equivalent of the Avalanche.
Notes
As may be taken from the title, the Great Fireball is basically an enlarged version of the trusty Fireball rune. In contrast to the single shot of a Fireball rune, the Great Fireball affects a huge area, up to 37 square metres! This way any average sized room is easily filled with the searing blaze, scorching all creatures that are in it except for the rune user himself. It stands to reason that the Great Fireball is a favourite of most Tibians, as it is well suited both to hit whole crowds of monsters and individual targets that are difficult to hit because they are fast or hard to spot. There are few adventurers who do not cherish those moments of silent glory when they have just brought down a whole crowd of enemies with a single Great Fireball. Still, due to the large blast radius the users are well advised not to be too trigger happy with this rune to make sure no friend is near when it is used.
History
In the Winter Update 2007, this rune changed from 2 charges to 4 charges, and the mana required increased from 480 mana to 530 mana.
The other significant change is that the magic words changed from adori gran flam to the current adori mas flam.
It used to look like this:
