sorry, landing rate depends on wit, int just increase mattac and m.attack critical damge Sorry, but why? Is there any proofs? My proofs: INT - m.atk, m.crit WIT - m.acc, m.eva, cast spd, m.crit chance, m.resist chance All debuf has min chance 10% and max chance 90% like in GOD dl = magic_level - target_level + 3 magic_level - magic level of debuf target_level - level of ur target clamped_dl = min(dl, 0) partial_chance = 30 + clamped_dl * lv_bonus_rate + activate_rate - basic_property_value lv_bonus_rate - constant for any debuf, e.g. stun shot - 1, silence - 2, etc activate_rate - constant too basic_property_value - value of basic property, that have impact to defence from current debuf. CON for stun, e.g. da = attacker_attribute - defender_attribute if da > 300: target_atributes_bonus = 1.7if 150 <= da < 300: target_atributes_bonus = 1.4if 40 <= da < 150: target_atributes_bonus = 1.2if 0 <= da < 40: target_atributes_bonus = 1.0 .. 1.2, linear functionif da < 0: target_atributes_bonus = 1.0 attributes_part = target_skill_attribute_multiplier * target_attributes_bonus target_skill_attribute_multiplier - target's defence from skill's attribute, including epics magic_multiplier = 11 * sqrt((1 + spiritshot_dmg_bonus / 100) * m_atk) / m_def spiritshot_dmg_bonus - 300 for BSpS and 100 for SpS m_atk - attaker's m.atk m_def - target's m.def And now assemble all it: chance = partial_chance * attributes_part * magic_multiplier * debuff_res_multiplier And note, that chance cant be less 10% and more 90% All information is taken from here: http://forums.goha.ru/showthread_0_0_t466573 and may be irrelevant. If u can correct me - i will be grateful
