我猜你是从这个链接http://irowiki.org/wiki/Acid_Bomb上面发过来的吧？

Type:  Offensive Skill  
Levels:  10 (fixed)  
SP Cost:  30  
Cast Time:  1 second  
Cast Delay:  1 second  
Range:  9 cells  
Element:  Neutral  
Catalyst:  1 Acid Bottle, 1 Bottle Grenade  
Prerequisites  
(Alchemist) Acid Terror Lv. 5, Bomb Lv. 5  

不过IROWIKI上面好像没说cast time: 1s是固定念咒吧？包括技能介绍（如下）也没提及。

Consume 1 Bottle Grenade and 1 Acid Bottle to hurl the contents of both items at a targeted enemy to inflict an amount of damage affected by this skill's level, the caster's INT and STR, the attack power of his weapon and the target's VIT. In PvP situations, Acid Bomb only inflicts 50% of its damage on other characters, but it may damage the targeted character's Weapon or Armor. This skill has a 1 second Cast Time followed by a 1 second Skill Delay, and consumes 30 SP per cast. Has a Skill Level's % chance to break weapon or armor.

对于咏唱时间么，置顶里面也有，IROWIKI上面的原文我也搬过来下算了。

Cast Time
While a few skills (Gravitation Field, Ganbantein, and Tracking, for example) have a fixed cast time, most skills' cast times can be reduced by upping stats and getting cast time reduction equipment/skills.

Each skill with reduceable cast time has two parts of cast times : a variable cast time and a fixed cast time.

The fixed cast time is always 20% of the original cast time and can only be reduced by special skills and special equipment; the variable cast time can be reduced by DEX, INT, Magic Strings, Suffragium and cast time-reducing equip/cards.

For Example: A skill with 10 seconds of total cast time has 2 seconds of fixed cast time and 8 seconds of variable cast time.

No matter how much INT, DEX and cast time-reduction equipment you have, you won't be able to make the cast time faster than the fixed cast time (in this case 2 seconds) with normal methods (unless you use special skills like Sacrament or Radius).

事实上有点固定念咒的感觉、、、、

和别人做了个测试，强火1s的固定吟唱时间，但是连续扔强火的话，需要考虑延迟和ASPD，极限应该就是1秒2下。
