idleLoops: Practical Magic

[MrNuggelz]

The Practical Magic tooltip states, that the mana cost of Smash Pots is decreased by 1% for every level, meaning that at level 100 the mana cost of Smash Pots should be 0.
But the in the javascript code the mana is computed by:
50 / (1 + getSkillLevel("Practical")/100)
producing a value of 25 for level 100.

So either the manaCost function should be changed to:
return Math.ceil(50 * (1 - getSkillLevel("Practical")/100);
or the tooltip should be changed.
