Harvest Soul - Spell

[Peacehagen]

Hi, I was just wondering if someone wanted to help me with a simple Drain spell here is the info:

Caster attempts to harvest the targets soul over 5 seconds. For each second spent channeling the target takes (5x Caster Agility) damage & the Caster is healed for 20% of damage done.
If the target dies from the spells damage, the Caster devours the targets soul and is healed for 20% of his/her maximum health.

P.S. I want a custom lightning effect, like a purple drain if possible.

If you have any questions please let me know. +Rep and credits will be given ofc

Thanks in advance
