Forge of the Gods AI [Commited]

Forge of the Gods AI.

Scarlet Stakato Noble
Assassin Beetle
Necromancer of Destruction
Arimanes of Destruction
Ashuras of Destruction
Magma Drake


- when HP is at : 20%
- chance to cast death bomb skill : +- 30%
- chance to spawn 5 clones on death : Not sure about chance. I set it to 30%

Rest of the FoG mobs just cast death bomb without spawning clones.



Note :
Make sure to remove skill 4614 from npcskills (IDs below)





Feel free to post suggestions on how to improve the code.

Hello Karakan, i just see this, i go to test it and do any devolution. Is this the last state? or have any more recent modifications?

PD: thanks for this nice contribution.

This is the final version ,which DnR commited with few fixes, around July.
If you see any flaws in the AI behaviour , feel free to let us know here in this thread.

Regards

Well, i had go to l2 off server, and kill manually 100 mobs scarlet stakato walker & scarlet stakato noble. 40 minutes aprox killing mobs :V

Results & differences:

First difference: on 100 mobs killed at most 5 used bomb skill. This give 5% aprox of probability to use bomb skill. On lisvus idk the %, but it is much bigger.

Second difference: on 100 mobs killed i obtain 9 mobs when they die they multiplied. This give 9% of probability to multiply when die. Later i kill 3 more and obtain other multiplication, I would dare to say the probability is 10%. On your is 30%, when i tested on lisvus before test on l2off i found it elevated, That's how it went.

Third difference: This is the most important, If i don't look and test bad, on your code, the multiply only given when monsters use skill bomb. My test with 100 mobs killed on l2 off, give me a result of, when monsters dies, have multiplied, without using skill bomb. i mean, they can multiply when die only. Without importance if is for "natural death" or using skill bomb. On your code if i'm not bad, only happend when use skill bomb.

I hope it helps.

Regards

Well, not really differences, just lower chances on the server you tested on, it seems.

Our current AI works like this..

- IF mob-hp lower then 20%  --> 30% chance for death bomb trigger
- On death -> 30% chance for spawn trigger


The triggers for spawning monsters and using death bomb skill are not linked.
It can happen that a mob dies without using the skill and still spawns monsters.

Which server did you test that on btw ?

I'm going to test this on L2Elite these days.

i tested it on L2ultra, but, when i tested on lisvus before test on l2off i found it elevated, is because i remember from others servers. But i dont know, i think this is a critery. And when you farm with polearms with this 30% i think is very OP, because spawns a lot of monsters if you array 30 monsters base before start killing it's so probabily you spawn new 45 mobs. more than double, to be exactly 150% more.
