[Hindori]

Now i need help with function in tfs 0.3.4pl2 (8.42)

I want to hp gain was counted from formula (hpgainamounts + skilldefense(what we have) * razyhp) but i don't now what function is to read what defence lvl player have. So my request is to change this code :

condition->setParam(CONDITIONPARAM_HEALTHGAIN, vocation->getHealthGainAmount() * vocation->getRazyHp());

for code from my formula.
