[Hytech]

How can I put kiel card effect on certain skill? for example bowlish bash...

bonus bDelayrate,-30;

 

[banhelba2019]

not really sure, why its in this itembonus group i cant say, but i dont see why its not possible, i just cant using itembonus

here 

pc.c

case SP_DELAYRATE:
if(sd->state.lr_flag != 2)
sd->delayrate+=val;
break;


and if you try to copy it to a itembonus2 script that has leveled i just get the pointer must be to object error

noticable difference is that lr_flag != 2 in the sp_delayrate script and the ones with skills names ==2 then break..

ok now the ones with skill names use this section in

script.c

case SP_AUTOSPELL:
case SP_AUTOSPELL_WHENHIT:
case SP_AUTOSPELL_ONSKILL:
case SP_SKILL_ATK:
case SP_SKILL_HEAL:
case SP_SKILL_HEAL2:
case SP_ADD_SKILL_BLOW:
case SP_CASTRATE:
case SP_ADDEFF_ONSKILL:
case SP_SKILL_USE_SP_RATE:
case SP_SKILL_COOLDOWN:
case SP_SKILL_FIXEDCAST:
case SP_SKILL_VARIABLECAST:
case SP_VARCASTRATE:
case SP_FIXCASTRATE:
case SP_SKILL_USE_SP:
// these bonuses support skill names
if (script_isstringtype(st, 3)) {
val1 = skill->name2id(script_getstr(st, 3));
break;






sorry im useless  tl:
