[Non-Renewal] Combo Cards

[ZX001]

Hello!

Good day to everyone! I would like to ask about the effects of combo cards, given the example below,

http://ratemyserver.net/index.php?page=item_db&comid=136

The Bloody Butterfly Card gives a +30% slower casting time while the Loli Ruri Card give a -15% faster casting time.

My question is does it disregard the original card effect of the bloody butterfly card of +30% slower casting time? Im quite confused  since if you do the math of +30% and -15% it give the result of +15% slower cast time.. but reading the combo script, it does give a -15% on the cast rate...

{ bonus bMaxHP,500; bonus bDef,5; bonus bMdef,5; bonus2 bSkillAtk,14,10; bonus2 bSkillAtk,19,10; bonus2 bSkillAtk,20,10; if(BaseClass==Job_Mage) { bonus bMatkRate,3; bonus bCastrate,-15; } }

Or does the combo set effect over rule the individual card effects?

Can anyone enlighten me? 

Thank you in advance

Ignore the info on the card, most of the time you will always find something wrong related to that.

In the end you will have 15% slower cast with the entire set.

Combo script applied after you complete the set. Individual item script still applied.

Bloody Butterfly scripts
bonus bCastrate,30; bonus bNoCastCancel,0; bonus2 bSkillAtk,"MG_FIREWALL",5;

Mage Combo cards sets
bonus bMaxHP,500; bonus bDef,5; bonus bMdef,5; bonus2 bSkillAtk,14,10; bonus2 bSkillAtk,19,10; bonus2 bSkillAtk,20,10; if(BaseClass==Job_Mage) { bonus bMatkRate,3; bonus bCastrate,-15

-15+30 = +15

Other example Incubus + Succubus set

Incubus
bonus bInt,-3; bonus bSPrecovRate,-20; bonus bMaxSP,150
Succubus
bonus bVit,-3; bonus bHPrecovRate,-20; bonus bMaxHP,1000
Combo
bonus bHPrecovRate,30; bonus bSPrecovRate,30; bonus bVit,4; bonus bInt,4

Results = 1 int , 1 vit , 10% hp/sp recovery , 1000 hp , 150 sp

Oh, so using the mage combo cards is a disadvantage on the casting time.. thats what i thought doing the math... that sucks.. -_-

I just wasted time getting those cards..  Whats the point of having those combo cards anyway?

Thank you very much ggwp and Triper
