Maximum value is INT_MAX, so 900M should still be okay, but try to just put something like 10000 for now (100x) rate.
 
Then you can debug here:
} else { // Weapon Forging - skill bonuses are straight from kRO website, other things from a jRO calculator [DracoRPG] make_per = 5000 + ((sd->class_&JOBL_THIRD)?1400:sd->status.job_level*20) + status->dex*10 + status->luk*10; // Base make_per += pc_checkskill(sd,skill_id)*500; // Smithing skills bonus: +5/+10/+15 make_per += pc_checkskill(sd,BS_WEAPONRESEARCH)*100 +((wlv >= 3)? pc_checkskill(sd,BS_ORIDEOCON)*100:0); // Weaponry Research bonus: +1/+2/+3/+4/+5/+6/+7/+8/+9/+10, Oridecon Research bonus (custom): +1/+2/+3/+4/+5 make_per -= (ele?2000:0) + sc*1500 + (wlv>1?wlv*1000:0); // Element Stone: -20%, Star Crumb: -15% each, Weapon level malus: -0/-20/-30 if (pc_search_inventory(sd,ITEMID_EMPERIUM_ANVIL) > 0) make_per+= 1000; // Emperium Anvil: +10 else if (pc_search_inventory(sd,ITEMID_GOLDEN_ANVIL) > 0) make_per+= 500; // Golden Anvil: +5 else if (pc_search_inventory(sd,ITEMID_ORIDECON_ANVIL) > 0) make_per+= 300; // Oridecon Anvil: +3 else if (pc_search_inventory(sd,ITEMID_ANVIL) > 0) make_per+= 0; // Anvil: +0? if (battle_config.wp_rate != 100) make_per = make_per * battle_config.wp_rate / 100; } Here you can check what make_per is before wp_rate is applied and after.

I won't give you a full guide but in general it's pretty easy:
 
1. Modify your router to forward the ports you use for RO to the computer you are using to run the server software on.
2. Make sure that computer has a fixed IP.
3. Set up IP and correct subnet in the conf files.
4. Tell your friends your external IP or give them an appropriate clientinfo.xml file.
5. ???
6. Profit

Was a bug on rAthena, I've fixed it now.

You need to either put the required exp values you want for levels above the official level or use the premade import file I prepared. After compile it should automatically be available in your import folder and look like this:
https://github.com/rathena/rathena/blob/master/db/import-tmpl/job_exp.txt
 
Follow the instruction at the top of the file.

Most of the skill's damage come from the cast cost, though.
 
https://github.com/rathena/rathena/blob/master/db/pre-re/skill_require_db.txt
 
// SkillID,HPCost,MaxHPTrigger,SPCost,HPRateCost,[...]
254,0,0,37:44:51:58:65:72:79:86:93:100,20,0,0,99,0,0,none,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0 //CR_GRANDCROSS

If you mean the @duel exploit, the fix is here: https://github.com/rathena/rathena/commit/c6ed8a4f92a143eca9ddc1c2161f88c1db9f70f4

Yeah put the skill ID you want the monster to react to as value.
1087,Orc Hero@MG_THUNDERSTORM,chase,21,20,10000,1500,5000,no,target,skillused,18,,,,,,, Like this means that Orc Hero will counter "Firewall" with the ranged skill "Thunder Storm".

Just don't use skill_damage_db then. It's harder to reorganize it to be applied first than it is to just put whatever damage code you want for your server in battle.c.
 
Basically you just want to half the damage for players but before you cap the damage, right?
 
So in battle.c:

case MO_EXTREMITYFIST: skillratio += 100 * (7 + sstatus->sp / 10); skillratio = min(500000,skillratio); //We stop at roughly 50k SP for overflow protection break;Just change it to e.g.
case MO_EXTREMITYFIST: skillratio += 100 * (7 + sstatus->sp / 10); if (tsd) skillratio /= 2; //Half damage for players skillratio = min(500000,skillratio); //We stop at roughly 50k SP for overflow protection break;

From the error message I'd expect it to look in a table named "picklog" for the column.
 
Did you create the log tables with logs.sql?
 
https://github.com/rathena/rathena/blob/master/sql-files/logs.sql
 
If you already have those then you probably missed an upgrade. You actually need to execute all SQL files in the upgrades folder: https://github.com/rathena/rathena/tree/master/sql-files/upgrades
 
At least all that were added after you've created your database.

Why so complicated?
 
Just go to src/config/core.h and comment the following line:
 
/// Uncomment to enable the job base HP/SP table (job_basehpsp_db.txt)
#define HP_SP_TABLES
 
Then it uses job_db1.txt instead of the tables.

src/config/core.h
 
#define HP_SP_TABLES

It's rather normal as some classes really get less HP/SP on level up from 99 to 100. Super Novice for example has 109 SP at level 99, but 100 SP at level 100.
Most of the warnings you get above should only occur if you have increased the normal max level, though! For example if you have the Gangsi class implemented on your server and allow it to level above level 99, you might want to adjust the tables to support higher level HP/SP.

In other words you just need to enable the PRERE define.
Here: https://github.com/rathena/rathena/blob/master/src/config/renewal.h
It could be that you need to move some NPC positions as well as warp-in points depending on the client version you use. And maybe even make sure the grf map layout fits to the version. Most places that often bug out are Izlude and Morroc as they got changed frequently.

I'm not sure what you want to do with that.
But the error is just as it says, the object "state" has no variable "botcheck".
Everything sd can contain is defined in pc.h:
https://raw.githubusercontent.com/rathena/rathena/master/src/map/pc.h

I have exactly the same problem and couldn't really solve it in VS 2010.
 
Luckily this only prevents you from compiling in Debug mode, you can still compile in Release mode. Just find the combo box with "Debug" in it and change it to "Release".

"Unused variable" warnings can easily be fixed by simply removing the variable declarations. It tells you the file and the line.

Well the server uses the time defined there, so the protection should stop after 7 seconds which your change.
 
Is it just the animation? Then I guess you'd need to modify the animation itself on the client.

It works fine in the current Git version you can get from:
https://github.com/rathena/rathena
You can find the bonus in pc.c in function pc_checkbaselevelup:

} else if( (sd->class_&MAPID_BASEMASK) == MAPID_TAEKWON ) { sc_start(&sd->bl,&sd->bl,status_skill2sc(AL_INCAGI),100,10,600000); sc_start(&sd->bl,&sd->bl,status_skill2sc(AL_BLESSING),100,10,600000); }

You need to sum it up in a hexidezimal way. It's easier like that because each digit is NOT influenced by other digits.
 
It goes like this:
0-9
A - 10
B - 11
C - 12
D - 13
E - 14
F - 15
 
0x80 + 0x10 = 0x90
 
If you have:
0x80 + 0x08 + 0x02 you can split that into:
 
First digit: 0x80 (8)
Second digit: 0x08 (8) + 0x02 (2) = 0x0A (10)
 
Then combine it together: 0x8A
 
0x just means "the following number is in a hexadecimal system" rather than the decimal system most humans use.

{ bonus2 bSubEle,Ele_Wind,50; bonus2 bSubEle,Ele_Earth,-50; }

Most ATK/DEF stat changes are not actually visible in the character window, make sure it's not increased by comparing the damage.

Right now each Vit increases HP by 1%.
 
In status.c:
status_calc_maxhpsp_pc  
Find:
max = job_info[idx].base_hp[level-1] * (1 + (max(stat,1) * 0.01)) * ((sd->class_&JOBL_UPPER)?1.25:1);  
If you want to double the effect of vit you need to change the 0.01 to 0.02.

Easiest solution would be to just make the ticket unstoreable and then let the NPC delete all tickets regardless of how many tickets the player has. That's effectively the same and doesn't require source code edits.
 
If you want to do it so that even on share parties the item always goes to someone who hasn't gotten it yet, then you need to code some algorithm for that in party.c:
int party_share_loot(struct party_data* p, struct map_session_data* sd, struct item* item_data, int first_charid) That's the best place to put it, you have all the info you need (struct item* item_data contains information about the item so you can check if it's your item).

Why not just remove them from the spawn files?

Number of hits is handled in the skill_db.txt: https://rathena.svn.sourceforge.net/svnroot/rathena/trunk/db/pre-re/skill_db.txt

But damage of each hit is handled in battle.c: https://rathena.svn.sourceforge.net/svnroot/rathena/trunk/src/map/battle.c
                    case SL_SMA:
                        skillratio += -60 + status_get_lv(src); //Base damage is 40% + lv%
