Patch changes

Hotfix (2024-02-27): Tooltip revised to clarify functionality. This rune periodically grants mana every 5 seconds, equal to 15% of the Shaman's intellect. Some potential timing issues that could have sometimes made it give less mana than intended have been fixed.
Hotfix (2024-02-14): Power Surge gained during a [Lava Burst], [Lightning Bolt], or [Chain Lightning] cast will no longer be consumed by that cast (since it does not benefit).
Patch 1.15.1 (2024-02-06): Added.
