Testing Skill's Chance
On Lineage 2, all skills that has a negative effect, such as stuns, debuffs, holds, slows, etc., have a certain chance and a respective resistance status that can be increased with certain itens and buffs, so it's very important to make tests about the chance of these skills or at least look carefully while you're using them at the fight to see if they're working or you're just wasting your fight time and MP, because if the skill's chance is too low, sometimes it's not worth to keep using it very often.
Test Conditions
First of all, you must make the test of the skill's chance against a class that you will use that skill, and try to do it with the same symbols, clothing set, jewels and buffs that he usually uses against you. The reason for these conditions is because it can drastically affect the final result of your test because of the resistence status, for example if you will test the Shield Stun chance against a Duelist, he already have a strong resistance against stuns, and you need to consider if your opponent will have a Zaken's Earring and a Earring of Antharas, because both of them increases shock/stun resistance.
Duelists have also Lionheart and War Frenzy that increases shock resistance, plus the high CON points. Now if you test the chance of the Dryad Root skill, you need to consider that Imperial Crusader set, Ring of Queen Ant and Ring of Baium gives hold resistance, plus Lionheart and Mental Shield from the staffs that increases this resistance as well, so don't forget to consider all the factors that can give some resistance for the opponent against your skill, and your equipments must be always the same while you're testing a skill's chance.
Making The Test
To do the test, you need to use the skill 10 times at the other character and count how many times the skill works, let's say if the skill works 4/10, then it's chance is 40% under those conditions, but it's best for you to do this at least five times to be sure. Most times you can see if the skill fails or works in the chat through the message it shows, like in the image, and for some skills you need to wait them to go off to try it again, because their time is not renewed.
