Starlight's Touch Mana cost

is in a pretty good spot, but one thing that bothers me tremendously is how upgrading Starlight's Touch beyond Rank 2 is basically a downgrade in his regular combat loop.

Most commonly, you'll be casting it after every two empowered attacks, only holding off if you need to cast another ability. Even at the best case scenario, you will be using the ability after 4 strikes, which makes Rank 5 almost completely redundant, yet it still increases the mana cost.

It would be really nice to investigate a rebalance to the ability that eliminates the scaling mana cost or some other way to make putting ranks into it felt like an actual gain, instead of a net loss of combat efficiency.
