N>Help on Skill, Increase Cell Area Effect

[Kiel]

Examples:

Sanctuary, Heavens Drive, Thunder Storm etc. has 5x5 cell area effect, how to make it 7x7 cells?

I've tried skill_unit_db.txt

but the problem is the graphics shows a 5x5 cell heavens drive only.. but damaging a 7x7 cells.

Am I doing it the right way? maybe there's a better way.. or how do I solve the graphics problem? Screen Shot below.. 

Thank you.

if damage do on 7x7, then you're doing in right way
