The skillset pretty much made me dissapointed, unless they're still holding up for other future skills. I was hoping that Golden time could remove/lower cooldowns or activations for either a charge from a water/flame/sand or to unlimited use of heatbuster without having to accumulate offensive alchemy to activate it.
with Elemental wave comes a gauge that you fill up by using Alchemy skills, it progressively gives you hp/mp/sp, once full you can use Elemental wave at the cost of losing the hp/mp/sp. But Golden time allows you to use Elemental wave every 5~3 minutes without touching your Alchemy gauge.
Hydra sounds like summon (like golem) but attacks on its own and deals water damage to mobs within the radius of the attack. Just like Uroboros fire breath. - This is the only skill I consider good in comparison to the other ones mentioned before.
Its extremely useful for small rooms, such as tara castle missions or orb rooms in Taill missions.
