Description

Acid Demonstration Max Level: 10 Skill Form: Physical attack - Misc Damage Description: Attacks an enemy by throwing both a Bottle Grenade and an Acid Bottle, inflicting an amount of damage that is affected by the skill's level, the caster's INT and the target's VIT. This skill only inflicts 50% of its damage on other players, but it has the chance of damaging that player's weapon or armor. The damage dealt by each hit of Acid Demonstration is: [0.7 * (INT^2) * VIT] / (INT + VIT). Consumes 1 Bottle Grenade and 1 Acid Bottle. [Lv 1]: 1 Hit, 1% chance of destroying [Lv 2]: 2 Hits, 2% chance of destroying [Lv 3]: 3 Hits, 3% chance of destroying [Lv 4]: 4 Hits, 4% chance of destroying [Lv 5]: 5 Hits, 5% chance of destroying [Lv 6]: 6 Hits, 6% chance of destroying [Lv 7]: 7 Hits, 7% chance of destroying [Lv 8]: 8 Hits, 8% chance of destroying [Lv 9]: 9 Hits, 9% chance of destroying [Lv 10]: 10 Hits, 10% chance of destroying Comments: This skill deals massive damage to just about anything in the game, but even more so to enemies with high VIT. This skill's damage is forced Neutral, ignores enemy's DEF and FLEE and bypasses Auto-Guard, Parrying, Cicada Skin Shedding, and Mirror Image. Crusader's Defender does not reduce Acid Demonstration's damage, but equipment based Anti-Ranged reductions such as Horn Card and Alligator Card will work. Pneuma, Wall of Fog, Kaupe and Flip Tatami are all effective counters to this skill. If the target has 0 VIT, the skill will miss entirely. This can be achieved by using equipment such as Succubus Card or Dimik Card. Acid Demonstration's damage cannot be increased by +% damage effects, flat +ATK effects, buffs or anything else. It only looks at your INT, the target's VIT and the target's reductions. Demi-Human, Anti-Ranged and Anti-Neutral reductions are all effective.
