in char_skill.cpp, add this:

if ((dwVnum == SKILL_GEOMKYUNG || dwVnum == SKILL_GWIGEOM) && !GetWear(WEAR_WEAPON))

	            return false;

under this:

bool CHARACTER::UseSkill(DWORD dwVnum, LPCHARACTER pkVictim, bool bUseGrandMaster)

	{

	    if (false == CanUseSkill(dwVnum))

	        return false;

                    if 2==select

In exchange.cpp chage this:

if (0 == s_vDSGrid[wBasePos])

to this:

if (0 == s_vDSGrid[wPos])

and now you can exchange

you have to change this:

const int aiSkillBookCountForLevelUp[10] =
{
    3, 3, 3, 3, 3, 4, 4, 5, 5, 6
};

// ADD_GRANDMASTER_SKILL
const int aiGrandMasterSkillBookCountForLevelUp[10] =
{
    3, 3, 5, 5, 7, 7, 10, 10, 10, 20,
};

const int aiGrandMasterSkillBookMinCount[10] =
{
//    1, 1, 3, 5, 10, 15, 20, 30, 40, 50,
//    3, 3, 5, 5, 10, 10, 15, 15, 20, 30
    1, 1, 1, 2,  2,  3,  3,  4,  5,  6
};

const int aiGrandMasterSkillBookMaxCount[10] =
{
//    6, 15, 30, 45, 60, 80, 100, 120, 160, 200,
//    6, 10, 15, 20, 30, 40, 50, 60, 70, 80
    5,  7,  9, 11, 13, 15, 20, 25, 30, 35
};
// END_OF_ADD_GRANDMASTER_SKIL
