Ok here you need to do...
look for this line on skill.conf inside the battle folder...
// Using 'old' behavior for devotion vs reflect damage? (Note 2)
// Default is 0 (official). If 'devotion_rdamage' is > 0 (chance to devote the reflected damage),
// when player with devotion attacks player with reflect damage ability (item bonus or skill),
// the damage will be taken by the person who provides devotion instead the attacker.
devotion_rdamage: 0
// Officially, reflecting shield (SC_REFLECTDAMAGE) reflects physical damage by skill or normal attack.
// But if the target is being devoted, it ONLY reflects the damage for melee skill. (Note 1)
devotion_rdamage_skill_only: yes
and change it to this
// Using 'old' behavior for devotion vs reflect damage? (Note 2)
// Default is 0 (official). If 'devotion_rdamage' is > 0 (chance to devote the reflected damage),
// when player with devotion attacks player with reflect damage ability (item bonus or skill),
// the damage will be taken by the person who provides devotion instead the attacker.
devotion_rdamage: 100
// Officially, reflecting shield (SC_REFLECTDAMAGE) reflects physical damage by skill or normal attack.
// But if the target is being devoted, it ONLY reflects the damage for melee skill. (Note 1)
devotion_rdamage_skill_only: no
I hope this solve your issue about the reflect..
