Questions about monks healing ability

If you got multiple monks together casting heal will it stack? 

Will monks healing stack with the kings heal or does the strongest one overrule or cancel out the other one? 

the healing effect stack, so you see a faster/more regeneration of health 

I used the two monk strategy XD I frst summon a horde of knights and 2 monk in between them and that creates havoc. Non stop regeneration of health XD plus they heal each other too. it worked even better with insta power archer :stuck_out_tongue:

The monk could be a game changer at a higher level. Since it has the ability to attack FB, it could replace other blunt units esp. cannons.

Moreover higher monk order could give the healing power to keep your max. troops alive to cause the destruction.
