What bonus does Energy Shield receive from Telekinesis?

The games tells me that energy shield receives a bonus from telekinesis. But it does not say anything about the bonus. What bonus does energy shield get from telekinesis?

When I play with the Character Planner, I can not see any difference either.

This is energy shield level 20 with telekinesis level 1.

And this is enery shield level 20 with telekinesis level 20.

Solution 1:

Telekinesis gives synergy to:

Energy Shield: reduces Mana lost per point of Life by 0.0625 per level

Users of Energy Shield will probably find themselves maxing out Telekinesis for its unwritten synergy: each point into Telekinesis makes the points of Mana lost per damage ratio of Energy Shield 0.0625 more effective.
16 points are needed in Telekinesis to make 1 point of damage consume 1 point of Mana, down from 2.
