Does the Rune of the Monk's healing bonus stack with Aquatic Benevolence?

The 6-piece bonus for the Superior Rune of the Monk grants +10% outgoing heal effectiveness to allies.

The Elementalist trait Aquatic Benevolence increases healing done to allies by 25%.

Do these two bonuses stack to increase healing done to allies by 35%, or does Aquatic Benevolence override the bonus from the Rune?

Yes, multiple "outgoing heal effectiveness" effects will stack additively. If you combine Aquatic Benevolence with Rune of the Monk, outgoing healing will be increased by 35%.

I did some tests on this in Heart of the Mists by equipping a Rune of the Grove and traiting 0/0/0/6/0 for 1397 Healing Power, then observing the effects of my Soothing Mist on myself and others.

The base effectiveness of Soothing Mist was 150 HP/second on both myself and others. When I swapped the Rune of the Grove for a Rune of the Monk, the effect on others increased to 165 HP/sec. Adding the Aquatic Benevolence trait increased it to 203 HP/sec.

These numbers work out increases of 10% and 35% over the baseline of 150.
