How to increase splash counts besides upgrading angelic radiance?

My angelic radiance requires 5 skill points per upgrade and will only increase my splash count by 2

I have +14 splash count due to angelic radiance.

Yet I have 23 splash count.

How to improve that further?

I got tons of splash skip though but those are useless because the splash skip is higher than number of titans on my maximum stage.

Solution 1:

For "Heavenly Strike" splash count, there are a total of 3 ways to increase the numbers of stages you splash through:

With all 3 combined, you can splash 70 stages if I am not mistaken (splashed 63 with Angelic Radience level 24 + snap effect + Angelic Guardian set)
