Totem Stacking: Anything more recent than 2007?

Well, just tested it:

Despite the wording being similar on healing stream and mana spring, implying that they have a similar effect, the difference is that healing stream just makes some kind of environmental effect (NOT a buff to the characters) that heals, while mana spring buffs party members in range.

Healing stream stacks, mana spring doesn't. Which everyone probably knew, but I think now I have an idea of how these work a bit better.

Anything that provides a buff rather than an environmental effect doesn't stack - guess I'll figure out which ones provide buffs and which provide environmental effects
