L2J Server

I'm not realy shure where i must post this problem in order of that i put it in off-topic area.

I have an l2j-Server up and running l2jdp-Version 3242 and l2j-Version 1053

To solve my problem i have use the search funktion but i can't find anything.

Nobody on my Server can kill Monsters if they are more than 10 level over himself the result is that we make only "1 dmg".

Can please anybody help me where i can search to solve this or can help me to fix it.

Ps.: Sorry for my bad english and i hope anybody can understand what i mean

do you have the problem with every monster or just Raidbosses?

is this for normal attacks, skills or spells?

We have the Problem with all Monsters! Generally if the Monster higher at 9-10 Level you will only make 1 DMG.

That's effect comes only if you spell! The Mage's uses now her Blunt-Weapons and hit the Monsters. There you will have damage from 50-70

magic fail rate:

All spells have a chance to fail (do only half or even only 1 dmg). This chance rises with leveldifference between magiclevel of the skill (about the level you learn the skill) and level of the target.
if you want to disable this, open altsettings.properties and edit this:
to: MagicFailures = False

Doing 1dmg with spells, on mobs that are many levels higher than your char is absolutely normal and correct (as per retail). It gets better as you level up, assuming that you keep your spells up to date and only use new spells, just because of the fact that you get to learn spells more often.
In other words, if you have a level 12 char, the most recent spells are from level 7. So even fighting white (lv 12) mobs, there is a 5 level difference between the spell and the mob. This is an ok difference. Spells will do full damage. By lv 15 mobs (yellow for the said char), the level difference between mobs and skill will be 8...so you will start noticing spells only doing half damage occasionally. Fighting red (lv22+) mobs means 15 levels difference from the spell (eventhough it's only 10 levels from the char)! This is a pretty large difference and causes a very high chance of full spell failure (1dmg).

Similarly, buffers and summoners will start being very ineffective with their spells, as they level up. For example, a buffer who is level 70 still has no new nuke skills (except against undead). So a lv 70 buffer will still be using a spell that was learned at lv 14 (wind strike). In this case, the char will do 1 damage even against dark blue mobs!!! For example, a lv 40 mob will be 30 levels below the char, but this doesn't change the fact that it's 26 levels above the highest level of the spell! So the spell will fail...

Fulminus: What about a lvl80 nuker, he has skills lvl74, lvl76, lvl77, how can he damage Tyrannosaurus(lvl87)?

They will merely suffer a 27% chance to do half damage and a 3% chance to do 1 dmg

1.3^leveldiff % of all spells for a normal fail (1/2 dam)
again 1.3^leveldiff % of a normal fail for a complete fail (1 dam)

if the mob is 10 or more levels higher than you, even normal fails will only do 1 dam

Fail rate on T-Rex for lvl 78+ char:
lvl 74 skill -> ~30% fail / ~9% complete fail
that means: of 10 nukes 1 will result in 1 dam and 2 will be halved. 7 will do normal damage so a nuker will still have ~80% of his maximum damage output in this case

lvl 76 skill -> ~18% fail / ~3.25% complete fail
lvl 77 skill -> ~13.75% fail / ~1.9% complete fail

with lvl 70 skills you will have a lot of fails (3 of 4 spells do only 1 dam) but still a result of about 20% damage output - lower skills will always fail!

Ah yes...I miscalculated a bit.
It's not' 27% for half and 3% for 1HP as I had said in my previous said. Slyce is right. It is 21% for half damage and 9% for 1HP. Still leaving you with 70% chance for full damage. That's using a lv 74 skill against a lv 87 mob.
