Question on TK and ES

[Paracite]

Each point in Telekinesis makes Energy Shield's damage absorption more effective. By default, for each point of damage absorbed by Energy Shield, 2 mana points are deducted - a 200% ratio. Each hard skill point in Telekinesis makes Energy Shield 6.25% more effective. For example, with 8 points in Telekinesis, 1.5 mana points are deducted for each point of damage absorbed - a 150% ratio. With 16 points in Telekinesis, one point of damage absorbed equals one point of mana loss - a 100% ratio.
