I found that my spell casting proficiency increases for my cleric even when I multiclass as a fighter.
The Divine Strike description says "When you reach 14th level, the extra damage increases to 2d8." and does not explicitly say I have to be 14th level of cleric. If I am 11 levels Tempest Cleric/ 3 levels Eldrich Knight = 14 levels total, will I get the 2d8 damage with Divine Strike?
