簡單的說，提升 egingin 的各級(紅級例外)所加的 buff 值，
以及讓 egingin 也支援 heart_buff(for 今天的拍賣會)。
以白級為例:
case 400..499: lv=12; // 白級, +air,str,con,dex,armor,hit,dam,speed
k=lv*6; // 本來 5 改成 6
// 讓 egingin 支援 heart_buff
k=k*(100+(int)me->query("heart_buff/egingin"))/100;
me->temp_several_same_mod(({"stat/air","stat/str","stat/con","stat/dex"}),
k,"egingin",TT);
k=sk*5;
k=k*(100+(int)me->query("heart_buff/egingin"))/100;
me->temp_several_same_mod(({"armor_class","speed","damage","dodge"}),
k,"egingin",TT);
