"Saving some for later" -Azanor
This allows for you to draw as much primal vis from a node as is safe for the node. If a node is drained to 0 in any aspect, it is likely to be damaged, losing the aspect permanently or having its recovery speed permanently reduced. However, if even one point remains, the node will recharge normally and completely over time.
This discovery allows you to automatically leave a point of each aspect in the node, so the node is not damaged. Warning: This ability does not work when using wands made either with plain wood cores, or with iron or copper caps.
Aspects required for ResearchEdit
You now have better control over the amount of vis you draw from nodes. You will always leave at least one vis of each aspect in the node, unless you are sneaking.
Be warned, this level of control is not possible when using wands crafted from normal wood and iron (or copper).
