In src/map/skill.c, find:
case MO_BODYRELOCATION: if (unit->movepos(src, x, y, 1, 1)) { #if PACKETVER >= 20111005 clif->snap(src, src->x, src->y); #else clif->skill_poseffect(src,skill_id,skill_lv,src->x,src->y,tick); #endif if (sd) skill->blockpc_start (sd, MO_EXTREMITYFIST, 2000, false); } break;
Remove:
if (sd) skill->blockpc_start (sd, MO_EXTREMITYFIST, 2000, false);
And recompile.
