Further Information

A mana spreader pointing upwards and with a mana pool right above it wont fill the pool. Hovering with the wand of the forest on the spreader wont highlight the pool as the receiver. A pulse mana spreader with the same setup will shoot through the pool.

There are some exceptions however:

• If the spreader is equipped with a potency lens, it will fill the pool (most other lenses wont work. I only tested a few)
• For the elven mana spreader it's the opposite: It can fill a pool above it without a lens and with most lenses, but not with a potency lens
• The Gaia mana spreader wont work with or without potency lens at all

On the image you can see from left to right the following setup:

1. Mana Spreader
2. Mana Spreader with potency lens
3. Pulse Mana Spreader
4. Elven Mana Spreader
5. Elven Mana Spreader with potency lens
6. Gaia Mana Spreader
7. Gaia Mana Spreader with potency lens
