Kundali's Guardian Seal

Skill: Summons a small Kundali guardian for 30s (if the Agility-linked ally is Lightning-aligned, elemental attack +10). Every 7th basic attack casts the magic skill 'Diffusion' on ground/air mobs, inflicting 3s of critical-hit vulnerability on grade-10+ mobs. Lightning Strike damage = ATK*2 + AGI*6; Diffusion damage = ATK + AGI*7.
