# FAQ
Is HY Storyline Mandatory? 
## Yes.
#### 💡 Lv. 10 - **The Missing Trainee 3**
* Nimbus Cloud (Flying)
**Note:** Lock Nimbus Cloud to continue using up jump!
#### 💡 Lv. 200 - **Sealing the Fiends: The Final Act 2**
* Exclusive Spell (Echo)
* Fiend Seal (ATT +10%, Final Damage +10%)
Is HY a Combo Class? 
### No. We don't Combo.
Different skills have different uses so play around with them to adapt to the situation
Does HY need Cooldown Reduction/Reset?
### We don't need CDR Hat or CD reset IA
We cut off 1-2sec of our AoE skills with CD hat but it wont change anything, cooldown skipping IA is unreliable and we have natural resets from our V skill.
*However* CDR Hat can be used for training if Consuming Flames is required in every rotation.
The loss of main stat to all our burst skills to increase the damage to Cudgel  is not worth it.
Attack Speed Modifiers?
In addition to our  Booster, Hoyoung only requires both
**1.**  **Decent Speed Infusion** AND
**2.**  **Green Pot** to hit AS0
### We do not need AS+1 IA
### KMS vs GMS
GMS gains 6-7% FD from AS0 on a dummy compared to KMS\
Will be less in practice due to movement in boss fights
