Drop Rates

[Talaysen]

Hi all.

I've had some players on my server concerned about the drop rates.
We have 1x/1x/1x drop rates, yet @mobinfo displays 0.00% drop rate for certain mobs.

IE: @mobinfo poring shows a drop rate of 0.00% for the poring card.

 

As far as I can tell everything is configured correctly, however.
 

Some of the monsters(e.g. hydra, flora, thara) card drop rate is 0.00%. Using the command @mobinfo, you can see the drop rate of the item the monster drops.

Some of the monsters drop rate are normal..
But majority of the monsters droprate as I searched using the command is 0.00%(even poring )

Even other items are affected(sohees- nurse cap, munaks - ninja suit)

ur :

 

item_rate_card: 100
item_rate_card_boss: 100
item_drop_card_min: 1
item_drop_card_max: 10000
 

Change :

 

item_rate_card: 100 >>>>>>>>>>> For nomal monsters
item_rate_card_boss: 100 >>>>>>>>>>>>>> For Boss monsters
item_drop_card_min: 100        >>>>>>Min possible drop rate for an item to drop
item_drop_card_max: 10000 >>>>>>>>>>At max a monster can drop this item.
 

 this is because , all drop rates are actually multiplied by the monster selfdrop rates, go on ratemyserver and check each drop rate for monster, for example

 

Poring has card drop rate 0.01% , and ur drop rates is set to 100.

So , now the actual drop rate would be 100x0.01% = 1% on total. same for all ,

 

There is xantara's patch for Drop rate seprator you can use it, and modify it for cards too.

 

Hope i helped, And Please correct me if i m wrong.

[Talaysen]

I think I understand, so the item_drop_card_min being 1 was actually lower than 1%.

 

Should I change all of the minimum rates from 1 to 100?

 

Edit:

 

With these settings:

// Item drop rates (Note 2)

// The rate the common items are dropped (Items that are in the ETC tab, besides card)
item_rate_common: 100
item_rate_common_boss: 100
item_drop_common_min: 100
item_drop_common_max: 10000

// The rate healing items are dropped (items that restore HP or SP)
item_rate_heal: 100
item_rate_heal_boss: 100
item_drop_heal_min: 100
item_drop_heal_max: 10000

// The rate at which usable items (in the item tab) other then healing items are dropped.
item_rate_use: 100
item_rate_use_boss: 100
item_drop_use_min: 100
item_drop_use_max: 10000

// The rate at which equipment is dropped.
item_rate_equip: 100
item_rate_equip_boss: 100
item_drop_equip_min: 100
item_drop_equip_max: 10000

// The rate at which cards are dropped
item_rate_card: 100
item_rate_card_boss: 100
item_drop_card_min: 100
item_drop_card_max: 10000

// The rate adjustment for the MVP items that the MVP gets directly in their inventory
item_rate_mvp: 100
item_drop_mvp_min: 100
item_drop_mvp_max: 10000

// The rate adjustment for card-granted item drops.
item_rate_adddrop: 100
item_drop_add_min: 100
item_drop_add_max: 10000

// Rate adjustment for Treasure Box drops (these override all other modifiers)
item_rate_treasure: 100
item_drop_treasure_min: 100
item_drop_treasure_max: 10000

 

This should correctly set 1% drop rates?

When I logged back in and check the Hydra card, it was saying 0.50% chance of drop.

Hello,

 

I also have the same problems befor i updated my svn it worked now it dousent i tryd everything but also my drop% arent going higher than 50%

Players ingame see wanderer card drop 1,4% i see 1% also very weird

[Talaysen]

It's the renewal drop rate modifier that does that.

[GM Henry]

Thank you for the replay.

Is there something i can do to use the normal drop rates in my renewal server?

[Talaysen]

http://rathena.org/wiki/SRC/config/#RENEWAL_DROP

For Example, if you are level 50, and you kill a monster
level 10, which normally drops a item at 50%, for you it'd drop at 25%
(because you're 30 levels or higher than it) How to Disable

• Commenting it's #define RENEWAL_DROP line out makes it disable (add // before #define)

 

Edit:

 

#define RENEWAL_DROP

 

becomes

 

// #define RENEWAL_DROP

[GM Henry]

Thanx again for the replay.

I went to the src\config\renewal.txt (h)  added \\befor it but dident change anything it looks still active,

Do you have any more advice i could do or try? or did i forget something

[Talaysen]

It should be //, not \\, also:

Any time you change your rAthena source code (the rAthena files) you need to stop the server, recompile, and start the server.

 

I use linux, so this process is:

 

./athena-start stop

 

make clean && make sql

 

./athena-start start
