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、、、、
