🌾 Five Levels In

If I only upgrade Paralysis to Level 5, the destruction duration increase is 170. The first four steps add 30 each, so the number moves 50, 80, 110, 140, 170.

🌾 Ten Levels In

A stop at Level 10 gives a destruction duration increase of 350. Across the five steps after Level 5 the values add 30, 30, 30, 40 and 50, so the number reaches 350.

🌾 All Fifteen

Level 15 is the far end, and there the destruction duration increase is 600. The last five steps add 50 each, so the number ends at 600.

Can Level 10 be enough for how you use Paralysis, or is the push to Level 15 worth it?
