Modify Firebolt, Coldbolt, Lightningbolt

[Cheria]

Hello Everyone.

I want to modify the damage of this 3 skills, but i cant find the damage formula on battle.c, or any other important .c

This is the only formula i find but i suppose its related just with spellfist because i already changed the numbers and didnt work.

I think its the same problem that other person haves with Jupitel thunder, i cant find it neither.

			   	 case MG_COLDBOLT: {
						struct status_change *sc = status_get_sc(src);
						if ( sc && sc->count ) {
							if ( sc->data[sC_SPELLFIST] && mflag&BF_SHORT )  {
								skillratio += (sc->data[sC_SPELLFIST]->val4 * 100) + (sc->data[sC_SPELLFIST]->val2 * 100) - 100;// val4 = used bolt level, val2 = used spellfist level. [Rytech]
								ad.div_ = 1;// ad mods, to make it work similar to regular hits [Xazax]
								ad.flag = BF_WEAPON|BF_SHORT;
								ad.type = 0;
							}
							if( sc->data[sC_AQUAPLAY_OPTION] )
								skillratio += skillratio * sc->data[sC_AQUAPLAY_OPTION]->val3 / 100;
						}
					}
					break;
				case MG_FIREBOLT: {
						struct status_change *sc = status_get_sc(src);
						if ( sc && sc->count ) {
							if ( sc->data[sC_SPELLFIST] && mflag&BF_SHORT ) {
								skillratio += (sc->data[sC_SPELLFIST]->val4 * 100) + (sc->data[sC_SPELLFIST]->val2 * 100) - 100;
								ad.div_ = 1;
								ad.flag = BF_WEAPON|BF_SHORT;
								ad.type = 0;
							}
							if( sc->data[sC_PYROTECHNIC_OPTION] )
								skillratio += skillratio * sc->data[sC_PYROTECHNIC_OPTION]->val3 / 100;
						}
					}
					break;		
				case MG_LIGHTNINGBOLT: {
						struct status_change *sc = status_get_sc(src);
						if ( sc && sc->count ) {
							if ( sc->data[sC_SPELLFIST] && mflag&BF_SHORT ) {
								skillratio += (sc->data[sC_SPELLFIST]->val4 * 100) + (sc->data[sC_SPELLFIST]->val2 * 100) - 100;
								ad.div_ = 1;
								ad.flag = BF_WEAPON|BF_SHORT;
								ad.type = 0;
							}
							if( sc->data[sC_GUST_OPTION] )
								skillratio += skillratio * sc->data[sC_GUST_OPTION]->val2 / 100;
						}
					}
					break;

Thank You!

If not mistaken. They don't have formula because they act as BF_MAGIC which if not defined will read your MATK as damage.

as

skill_attack(BF_MAGIC,src,src,bl,skillid,skilllv,tick,flag);

Darristan is correct, those spells have their damage based off your MATK (100% per bolt) and therefore you'd have to re-create the skill calls to reduce your MATK similar to some other mage skills (I think Napalm Beat starts at a reduced percentage, I'm not sure off the top of my head).

Another solution, one I'd recommend, is to reduce the amount of bolts based on skill level, such as 1 bolt per 2 skill levels, this would effectively halve the damage done at skill level 10 and doesn't require source editing. This can be done by editing your skill_db.txt. Let me know if you need help doing so and I'll show you how.

If you wanna increase the damage, I recommend you take a look at this.
