In this experiment, we will test the https://l2wiki.com/Ignore_Divinity skill land rate and the sequence of cancelling buffs. Attacker: 99 lvl Feoh Mystic Muse, no buffs, no equipment Target: 103 lvl Iss Hierophant, no equipment, 2, 5 or 8 buffs without cancel protection. In the first experiment, we tested the land rate and the number of buffs canceled. The results are summarized in the following table: Number of buffs canceled:2102 buffs5,50%48,50%46,00%5 buffs40,75%37,75%21,50%8 buffs74,50%19,00%6,50% We performed 400 tries in the attempts with 5 buffs and 200 in the rest. Result: As you can see, the more buffs you have, the higher the chance is to cancel more of them. When we put down the 5 buffs attempts, we also wrote down the buff slot number to see if it's possible to "protect" some buff by casting it in the beginning or in the end of a buff sequence. Slot12345Times canceled per 10022,7526,0022,2521,7526,50 The table reflects average slot cancel rate as we had situations where 2 buffs were canceled. Result: As you can see, every slot was affected. And if you try to protect a certain buff by overbuffing, you'll get the following cancel situations: For 2 buffs: (5.5*2+48.5)/2 = 29.75 For 5 buffs: (40.75*2+37.75)/5 = 23.85 For 8 buffs: (74.5*2+19)/8 = 21 Conclusion: The buff canceling system looks complicated enough to see that the developers tried to balance the land rate for various situations. It looks like they tried to achieve equal slot cancel rate for any number of buffs.
