/*
According to sniffs there are multiple spawn groups (5 to be precise) since Living Poisons with the same initial spline
destination are only getting spawned in 31 seconds intervals. For the sake of readability we will stick
with one and increase the interval.
Here are some values:
- The "Frogger" spawner spawns the same group in 31 second intervals. Since we are lazy and wanna keep the values readable
we stick with one timer set at 6s.
- The slime moves with a spline velocity of 2.5f which equals the walk speed of it.
- If a slime explodes it will despawn 8.5s after its death.
- If a slime reaches its final spline destination it will despawn after 500 milliseconds -+ 100 depending on Blizzard's packet interval
