Hydra

Hydra is a Sorcerer skill from the Conjuration skill tree. Its features are:

Grants Player	Exploits Condition
Fire Dmg	Critical Strike Damage
Burning Dmg (DoT)

Pyromancy

'Creates Condition' means this skill creates this condition i.e it could make a target Vulnerable that other skills can take advantage of. 'Exploits Condition' means this skill takes advantage of a condition, not necessarily of its own making. So for example another skill might Stun and this skill could take advantage of that.
