Guild Wars 2

Would like to confirm (2) give 3 stacks of might to nearby allies when using a heal skill, and (6) give fury to nearby allies when using a heal skill. Does the empower skill on the staff, altru-healing and monk’s focus in the trait activate them?

Also what is the range for allies to be affected by them.

No clue about the range, only way to find out is test this on a dummy.

But the (2) and (6) only apply when using your healing skill #6

This is the case with every instance where a tooltip says ‘heal skill’.

BigTeeHunter is correct. Only your #6 skill counts. I have yet to see any figures on the range, and the range of similar effects isn’t consistent enough to assume one. Rune of the Monk, for example, is 1000, but Rune of the Centaur is 600.
