Summon Hydra is a level 7 Summoning spell which summons a friendly hydra.


A hydra with 4 to 12 heads is summoned. Number of heads depends on power, but it's always rare to get more than 8. Duration of the summon is always very short, around 9 turns.

Number of heads is (1d<power> - 1) / 6, but at least 4 and at most 12. There is always 5 out of 6 chance that the number of heads is limited to 8.[1]
