Summons a many-headed hydra to fight alongside the caster for a short time. Spell power determines the number of heads.

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

Useful Info

A hydra with 4 to 12 heads is summoned. The number of heads depends on spell power; the hydra will have (1d<power> - 1) / 6 heads, but there is an 83% chance that its heads are capped at 8.^[1]

The duration of the summon does not depend on the spell power and is always very short, around 9 turns.

There is a summon limit of 2; additional summons will cause the oldest to very quickly time out.

Strategy

Summon Hydra effectively takes the role of a Conjurations spell to a summoner. Hydras offer a high damage per turn, but since they have poor durability and time out very quickly, this spell has a relatively poor MP efficiency. Useful if you want to kill something quickly.

Monster Version

The following enemies cast Summon Hydra:

d Bai Suzhen

Note that Bai Suzhen cannot cast this spell while in the storm dragon form.

History

Summon Hydra was added in 0.8.
